COATING FORMULATION AND APPLICATION OF ORGANIC PASSIVATION LAYER ONTO IRON-BASED RARE EARTH POWDERS Cross-Reference to Related Applications This application claims the benefit of priority of United States Provisional Patent Application No. 60/524,633, filed November 25, 2003, the disclosure of which is herein incorporated by reference in its entirety. Field of the Invention The present invention relates to coating formulations for rare earth-transition metal-boron (RE-TM-B) magnet materials, such as neodymium-iron-boron type magnetic powders manufactured from rapid solidification processes for, among other things, the purpose of corrosion and/or oxidation resistance when exposed to aggressive environments or for passivation. The present invention also relates to methods of applying coating formulations to rare earth-transition metal-boron (RE-TM-B) magnet powders. Background of the Invention Isotropic polymer bonded rare earth permanent magnets have been used in various advanced motors and electronic devices. With the miniaturization of motors and electronic devices, it is necessary to reduce the size of magnets used. To enable effective miniaturization and efficient energy or signal output, it is essential for these applications to demand magnets of high flux densities. Factors determining the flux density of isotropic polymer bonded magnets can be divided into two parts: the type of magnet materials used and the volume fraction of the magnet materials in these polymer bonded magnets. The criteria for selecting the type of magnetic materials are strongly influenced by the operation conditions demanded by the given applications. The polymer binder used for making polymer bonded magnets must be able to provide sufficient mechanical strength to hold magnet powder together and maintain the designed shape specification up to the intended operation temperature and to sustain that operation temperature without softening, deforming or breaking. The magnetic materials must provide sufficient flux to sustain the desired properties at the operation temperature without substantial loss of magnetization. The flux aging loss of a magnet material provides an indication of the magnet material's stability to heat and protection from corrosive and oxidative environments, which can affect the magnetic materials' ability to retain magnetic flux over time durations at certain temperatures. The flux aging loss of a bonded magnet ultimately determines the magnet's utility in various applications, and should be minimized if the bonded magnet is to be used for high temperature applications. The oxidative or corrosive degradation of the constituent materials and change in overall magnetic properties should be minimized to enhance the utility of the bonded magnets. The combination and amounts of the organic and magnetic materials should allow the desired properties previously discussed to be optimized and attained. The amount of magnet powder in the polymer-bonded magnets, typically stated as a mass or volume fraction, is determined by the polymer binder type, molecular weight of the polymer binder, and the methodology applied in order to combine said materials effectively. Depending on the molding method, various polymers are available for making isotropic bonded magnets. Compression molding, injection molding, extrusion and calendering are well-known means for producing polymer-bonded magnets in commercial quantities. Compression-molded or compacted magnets allow magnets to reach high, desirable volume fraction (greater than 83%) required to achieve strong magnetic properties. Typically, thermosetting polymers, such as, epoxies, phenolics, and other crosslinkable resins with their respective curing agents are used with the ideology of producing magnets that will less affected by heat or chemical attack than the non-coated powders. These materials are initially low molecular weight substances that can be easily applied as coatings for the magnetic powders. The components can be molded and cured to produce magnets that are resistant to high temperatures (typically, not much greater than 250 °C) and chemical solvents. The extent of crosslinking or the crosslink density of the thermosetting binder governs the coating's overall resistance to oxidation and corrosion as well as the mechanical strength of the final magnet At high loadings of solid filler the oxidation potential of the magnetic powders increases and becomes deleterious to the magnetic properties because of the low degree of organic protection, where the industry term "loading" refers to the proportion of magnet powder in the final magnet product. Chemical additives are introduced into the bonded magnet system in order to alleviate oxidative effects on the metallic filler particles. United States Patent No. 5,888,416 to flcuma et aL discloses the use of various chelating agents and antioxidants in the rare-earth bonded magnets of polyphenylene sulfide (PPS), nylon 12 (polyamide), and polyethemitrile (liquid crystal polymer) thermoplastic binders for use in extruded magnet compositions. United States Patent No. 5,395,695 to Shain et al. discloses incorporating successive layers of an antioxidant, an epoxy novolac resin, and polystyrene onto the magnet material for improvements in oxidation resistance, with an emphasis on the sequential layering of the components. Xiao et al. and Guschl et al. describe the benefits of incorporating an aminosilane coupling agent onto the powders within a polyphenylene sulfide binder. See L Xiao and J. U. Otaigbe, "High Performance, Lightweight Thermoplatic/Rare Earth Alloy Magnets," Mat Res. So. Svmp. Proa. 577:75-80 (1999); P. C. Guschl, H. S. Kim, and J.U. Otaigbe, "Effects of a Nd-Fe-B Magnetic Filler on the Crystallization of Poly(phenylene sulfide)," J. Appl. Polv. ScL. 83:1091-1102 (2002). However, the results disclosed in these references were based solely on magnets with powder loadings on the order of about 80%, which is lower than those achievable in compression-molding magnets (on the order of about 90% or more). United States Patent No. 4,876,305 to Mazany ("Mazany") describes the application of a combination of aminosilanes and epoxysilane coupling agents with epoxy resins for oxidation resistance, comparing oxidation rates to treated and non-treated samples. The concentrations of magnetic material in the magnets disclosed in Mazany were fairly low, the magnetic properties of the resultant magnets, e.g., the flux aging loss, are not considered relevant United States Patent No. 5,087,302 to Lin et ah discloses a process where an organotitanate is added to coarse Nd-Fe-B powders during a milling step to produce sintered magnets with improved magnetic remnance, coercivity and oxidation resistance. However, . since the milled magnet powder-organotitanate mixture is subjected to a high-temperature degassing technique in an inert atmosphere in order to manufacture the sintered NdFeB magnets, the organotitanate is removed or "degassed" from the metallic powders. Recently published coupling agents that have been utilized in bonded magnet systems are the organotitanates and organozirconates. Several Japanese patents describe the use of these agents and NdFeB powders with mainly nylon 12 resin, epoxy resins, PPS resin, and other such thermoplastic or thermosetting binders. See, e.g., JP-03165504 to T. Hitoshi et al.\ JP-03222303 to M. Yoshihiko; JP-04011701 to M. Yoshihiko; and JP-04257203 to T. Hitoshi et al. These disclosures are directed to applications to injection-molding and extrusion-produced bonded magnets, because the specification of the material types and compositions disclosed therein fall well below the magnetic powder loadings disclosed in the present invention. Chen et al. disclose that a diaminoethylene-based titanate incorporated into a NdFeB-epoxy-bonded magnet system improved the bonding of the components and overall specific density of the magnet. See Q. Chen, J. Asuncion, J. Landi, and B. M. Ma, "The Effect of the Coupling Agent on the Packing Density and Corrosion Behavior of NdFeB and SmCo Bonded Magnets," J. Appl. Phvs., 85:8:5684-5686 (1999). However, no mention is made of the effects of the titanate on the flux aging loss of the magnet material or of the method in which the titanate was incorporated into the system. The present invention provides a more effective technique for protecting rare earth-transition metal-boron magnetic materials through a performing liquid coating procedure on the rare earth-transition metal-boron magnet powders.

Detailed Description of the Invention The present invention provides coating formulations for rapidly solidified rare earth-transition metal-boron (RE-TM-B)-type bonded magnetic materials, and methods of applying such formulations to the magnet materials, with emphasis on their protection against oxidation. Specifically, the flux aging loss of any bonded magnet must be minimized in order for high temperature applications to be considered. While not being bound by any specific theory, it is believed that the incorporation of organic materials, such as polymers with the inorganic metallic powders provides a means to passivate and prevent oxidative tendencies by reducing the reactivity of the filler surfaces or by decreasing the permeation of energetic oxygen molecules to the filler surfaces. Additionally, the coated powders allow a higher degree of flexibility and moldability for producing bonded magnets. The coating formulations and processes of the present invention provide for bonded magnets with higher powder loadings, i.e., higher proportions of magnet materials contained in the final magnet, than achievable from other methods. Prior art references disclose * magnets with powder loadings lower than those achievable in the present invention, which is on the order of about 95% to about 99% or more by weight of the magnet For example, magnets made using, e.g., polyphenylene sulfide (PPS) or nylon 12 (polyamide), such as injection-molded bonded magnets, usually contain only about 85% to about 93% by weight or less of magnet powder, corresponding to about 50-70% by volume. The prior art for bonded magnets, using polymeric binders, has focused on dry blending techniques. These methods physically mix organic powders, such as thermosetting resins, with the magnetic powders in the absence of solvents. Compaction and/or compression molding are used in order to form the solid magnets by initially fusing the organic powder between the inorganic particles. These resultant magnets contain weakly bound particulates with nonuniformities and, as a result, a degree of porosity, which can be detrimental in terms of oxidation, flux aging loss, and overall magnetic and physical properties. Liquid coating techniques assuage these problems associated with dry blending by providing a uniform organic layer on the powders. This resulting uniformity provides more effective oxidation protection following the cure reaction of the thermosetting binder. Both liquid and solid, dissolvable resins and other additives are permissible for the application process. The polymer-coated powders of the present invention have improved thermal stability in comparison to the magnetic powders alone. Further, more effective protection can be achieved through the addition of particular specialty chemical additives. While certain antioxidants can be effective for protective purposes to some extent, the presence of the antioxidants only mildly deters oxygen molecules from reaching the filler surfaces. Because the antioxidant molecules are freely suspended within the binder matrix and deposited on the filler particles (such as in a physisorption process), they have limited ability in oxidation protection. In other words, little to no interaction between thermoplastic binders, filler particles and these additives may occur (such as in a chemisorption). Possible side reactions of binders with reactive epoxide functional groups of epoxy resins may happen if the antioxidant agent contains active amine groups. However, although complete protection from oxidation may not be possible for systems that contain solely antioxidants, their use does aid in oxidation prevention. Accordingly, the inventive formulations may optionally contain antioxidant agents to provide further flux aging loss resistance. Non-limiting examples of antioxidant agents include a butylated reaction product of p-cresol and dicyclopentadiene antioxidant, and tetrakis-[methylene-(3,5-di-tert.-butyl-4-hydroxy-cinnamate)] methane antioxidants. As used herein, the term "epoxy resins" refer to synthetic uncured or unreacted resins containing epoxide functional groups with an aromatic backbone. Non-limiting examples of epoxy resins include epichlorohydrin/cresol novolac epoxy resin and epichlorohydrin/bisphenol A epoxy resin types. The epoxy-based coated powders with the specialty additives (e.g., coupling agents, antioxidants, etc.) are in the uncured state prior to the manufacture of the final cured magnets. It has been discovered that coupling agents allow protection by way of altering the powders surface through beneficial chemical or weaker physical (hydrogen) bonding. It is believed that the coupling agents form protective layers on the powder that are compatible and potentially reactive, if appropriately selected, with the surrounding organic passivation coating, permitting additional interaction between the components of the magnet. The preferred coupling agents for application in the invention provide thermal stability to the magnet and limit oxidation. Organosilane coupling agents have been used extensively for organic-inorganic systems within aqueous and/or alcohol-rich solutions, due to their reactivity with surface hydroxyl chemical groups present on filler particles such as glass fibers, metal hydroxides, silica and silicates. A monolayer of reacted organosilane is formed on the filler surface through condensation, following the hydrolysis reaction in water. The amine-based silanes, or aminosilanes, are among the most commonly used silanes, due to the high reactivity between the lone pair electrons that reside on a nitrogen atom of primary, secondary and tertiary amines and the epoxide functional group of epoxy resins. The aforementioned reaction of the silane with the inorganic filler particle couples those two entities together, and the epoxy-amine reaction establishes a bond between the silane and epoxy resin. Ultimately, this creates a crosslinked structure involving every reactable component of the system. Due to their greater coupling effect and ease of reaction with filler particles in the absence of a solvent, organotitanate and organozirconates (which have similar reaction mechanisms) have received more attention than organosilanes in some respects. The organosilanes offer typically a single coupling site on the molecule with a single hydroxyl group on the filler particle, depending upon the extent of the hydrolysis and condensation reactions during pretreatment. The organotitanates or organozirconates allow at best three coupling sites, giving rise to more complete coverage of a monolayer. In addition to this information, organotitanates can also react with surface protons of inorganic filler particulates that may be devoid of hydroxyl groups. The organotitanate or organozirconate is also found to aid in the curing process to create the bonded magnet, possibly by aiding in the cross-linking process. These agents can be applied to filler surfaces via solvent-blending or direct melt-blending processes with the polymer binder and inorganic filler within a compounder or injection molder, which require no pretreatment. This invention focuses on the solvent-blending or liquid coating method of application. Because of the efficiency of these organic coupling agents, concentrations that range between 0.1 and 1.0 % (by weight) are sufficient for optimal properties (e.g. enhanced processing, mechanical strength, adhesion, and chemical resistance). This statement is particularly important for the manufacture of polymer-bonded magnets. The more coupling agents added to the system, then the lower the potential magnetic strength of the magnet will be, since the magnetic flux is directly related to the amount of magnetic material present The use of small amounts of the coupling agents allows appropriate coupling with minimal reduction of magnetic properties. Typical thicknesses of coupling agents are on the order of one micron at these concentrations mentioned. New materials are being added to polymeric systems called "nanofillers" or "nanoadditives" and are showing remarkable improvements in a system's thermal stability, mechanical strengths, oxygen permeability and processability. These additives are primarily inorganic and consist of a silica-based structure with organic functionalities. At least one of the spatial dimensions of said nanofillers is of the nanometer range (0.001 to 0.1 microns). With this minute dimension the aspect ratios tend to be on the order of 100 to 1000, which give rise to the mentioned improvements in overall properties. Typical concentrations of these nanofillers can vary within 0.1 to 10.0% by weight relative to the polymer binder. Examples of a currently used nanofiUer material are clay fillers (typically bentonite or montmorillonite). This material is modified, for example, with alkyl ammonium salts in order to guarantee proper compatibility with the matrix material. These "organoclays" are a popular new addition to the growing field of polymer nanocomposites for both thermosetting and thermoplastic systems. Specifically for thermosets, organoclays have been effectively incorporated either through high-shear melt or solvent blending. Effective dispersion of the organoclays' silicate layers throughout the polymer phase yields favorable property enhancement. Another family of the nanofillers distinction that has lately received much attention has the general name of polyhedral oligomeric silsesquioxanes or POSS. Polyhedral oligomeric silsesquioxanes or POSS are referred to herein as "POSS additives." These compounds are comprised of nano-sized silica-based cages with a vast number of organic functionalities. Proper selection of the most appropriate functionality, whether reactive or inert, can allow many polymeric systems to become hybridized into unique polymer nanocomposites. Through liquid coating with the organotitanates and/or organozirconates, nanofillers (e.g., organoclays, POSS additives) and antioxidants in the presence of an epoxy resin, dicyandiamide hardener, tertiary amine accelerator, and zinc stearate lubricant, the present invention provides a high-volume fraction bonded magnet by way of compression or compaction molding. The methods of the present invention retain the organotitanate coupling agent in the mixture during and after the steps of mixing the coating compositions with the magnet powder, as it is found that such intimate mixing between organotitanate and various components aids in yielding epoxy-bonded magnets with enhanced performance, such as improved flux aging loss. In specific embodiments of the present invention, the organotitanate or organozirconate coupling agent are admixed with the other constituents of the coating formulation. In other embodiment of the invention, the organotitanate or organozirconate coupling agent can be added to the magnet powder in a pre-coating step before introduction of the other constituents of the coating formulation. The addition of accelerator in the coating formulations of the present invention reduces the curing temperature for creating the bonded magnet from a temperature on the order of around 200°C or more to a temperature of around 170°C. The lower curing temperature reduces the possibility of oxidation of the magnet material during the formation of the bonded magnet. This is beneficial for providing a bonded magnet with a lower flux aging loss, and better performance. The addition of the lubricant results in lower ejection pressures for removing the bonded magnet from the die press, which helps prolong the life of the die press. The present invention also provides a coating formulation applicable to rare earth-transition metal-boron (RE-TM-B) magnet powders, such as neodymiurn-iron-boron type magnetic powders manufactured from rapid solidification processes for, among other things, the purpose of corrosion and oxidation resistance when exposed to aggressive environments. The coating formulation preferably contains an epoxy binder, curing agent, an accelerating agent, and a lubricant. By incorporating coupling agents and optionally, other specialty additives with the magnetic powder and the organic epoxy components additional oxidation and corrosion prevention, enhanced adhesion and dispersion between the filler and matrix phases can be achieved. This invention is applicable to all such rare earth-transition metal-boron (RE-TM-B) magnet powders produced by rapid solidification and encompasses both the bonded magnet products that consist of combinations of the materials mentioned and the application processes. Experimental testing of the magnets of the present invention revealed the exceptional properties derived from the coating formulations of the invention. Solvent or liquid coating is an effective manner in which each organic component can be blended with solid filler particles. It has been discovered that applying a low-viscosity, volatile carrier fluid containing dissolved low-molecular weight binder components and additives effectively allows the deposition of a protective, organic layer on the magnetic powders under ambient or moderate-temperature conditions. This procedure ensures a fast and simple production of compression moldable, liquid-coated, RE-TM-B powders for high-temperature applications. In another aspect, the present invention provides rapidly solidified rare earth-transition metal-boron (RE-TM-B) type magnetic materials with a protective passivation coating for high temperature and aggressive environment exposure. The bonded magnets are formed from the coated magnetic powders that have been compacted and subsequently cured. The resulting bonded magnets, that arise from the liquid coating process, including organotitanate coupling agents in the epoxy system, show significant improvement in flux loss aging as compared to magnets made without coupling agent at temperatures or exceeding 180 °C Figure 1 shows the stark contrast in flux aging loss at 180°C after 100 hours between magnets (operating at a load line PC = 2) formulated in the absence of coupling agents (No CA) or that have been liquid-coated with an organotitanate or organozirconate agent (LICA 38, KZ OPPR, KR 55). The presence of the organic coupling agent reduces the degree of oxidation of these powders, making them suitable for numerous high temperature/corrosive environment applications. Five embodiments of the present invention are disclosed, including one non-coupled magnetic powder system and four coupled magnetic powder systems for passivation. The exemplary coupled systems include a coupling agent-coated powder, a coupling agent-epoxy-coated powder and two coupling agent-nanoadditive-coated powders. In many embodiments, the present invention provides a magnetic material that has been rapidly solidified then thermally annealed, preferably within the temperature range of 300 °C to 800°C for about 0.5 to about 120 minutes. The magnetic material has the composition, in atomic percentage, of wherein R is any rare earth element including yttrium; M is one or more of and Si. Further, the values for u, v, w and x are as follows: Any number of therrnosetting polymer binders may be selected, such as, urea formaldehyde (amino resins), phenolics, thennosetting polyurethane resins, alkyd resins, or epoxy resins. Curing agents or hardeners contain functional groups that react with functional groups of the resin and are required to cause the crosslinking or cure reaction. Examples of curing agents are aliphatic (linear), cycloaliphatic, tertiary, and aromatic amines; amine adducts; amidoamines; polyamides; or anhydrides. Typically, these agents are added to the resin at about 1 to 6 phr (per hundred parts resin), depending on the desired extent of cure of the final crosslinked product. The accelerator, which increases the reactivity of the curing agent, can be a tertiary amine, e.g. imidazole, amine adduct, or amine-based complex, e.g. BF3 mono-ethylamine complex. Accelerator concentrations fall within the range of 1 to 4 phr. For ease of processing, a lubricant such as fatty acids, metal (e.g., zinc or calcium) stearates, fluoropolymer resins, polyolefin or polyester resins, etc. is used. Typically lubricants are measured relative to the amount of solid filler present. The concentration range of lubricant may be 0.01 to 0.5 phf (per hundred parts filler) and is dependent on the desired final properties of the resulting bonded magnet. Antioxidant concentrations tend to exist within the range of 0.5 to 1.5 phr (per hundred parts resin), and are useful for oxygen radical consumption in a system. The appropriate amounts of coupling agent and nanofiller (e.g., organoclay and POSS additive) for a specific system are determined empirically for optimization of its final desired magnet properties. Preferably the concentration ranges of coupling agent, organoclays and POSS additive added to the entire system should fall wifhin 0.1 to 1.0% by weight (based on amount of binder and filler), 1.0 to 10.0% by weight (based on amount of resin), and 0.1 to 1.0% by weight (based on amount of binder and filler), respectively. In a specific embodiments, a multifunctional epichlorohydrin/cresol novolac epoxy resin, with a dicyandiamide curing agent, a tertiary amine accelerator and zinc stearate lubricating agent in the polymer binder system are used for compression-molding purposes both including and excluding coupling agent Any of the following coupling agents are applicable to this invention: organosilanes, organotitanates, organozirconates, and organozircoaluminates. For these embodiments the recommended coupling agents for the epoxy-bonded RE-TM-B magnets are the organotitanates and organozirconates, which are of the general form The RO is the hydrolyzable group that reacts with surface protons or hydroxyl groups, where R may be short or long chained alkyls (monoalkoxy) or unsaturated allyls (neoalkoxy). Ti and Zr are typically tetravalent titanium and zirconium atoms, respectively, where both may have higher or lower valence as well. X is the binder functional groups, such as phospliato, phosphito, pyrophosphato, sulfonyl, carboxyl, etc. R is the thermoplastic functional group such as: aliphatic and non-polar isopropyl, butyl, octyl, isostearoyl groups; napthenic and mildly polar dodecylbenzyl groups; or aromatic benzyl, cumyl phenyl groups. Y is the thermosetting functional group that typically is reactive, e.g. amino or vinyl groups. n represents the functionality of the molecule. A functionality of n = 2 implies that there exist two reactive hydrolyzable groups and two organofunctional groups for compatibility with the polymer binder. Examples of the various functionalities of these coupling agents are displayed in Table 1. The liquid coupling agent organotitanates and organozirconates with pyrophosphato and phosphito binder functional groups were found to be most effective for oxidation resistance, due to their reactive nature with surface protons and hydroxyls present rm flip. msi vThe titanium and zirconium atoms may have coordination numbers greater than 4. AR is an aromatic benzene unit. The italicized, bold-type atom is the primary connecting atom of the functional segment Information taken from Ken React Reference Manual, The liquid coating process requires an appropriate solvent for proper dissolution of the organic resin, hardener, accelerator, lubricant and coupling agent Polar protic solvents, such as, alkanols or alkoxy-based alcohols and aprotic solvents, such as, ketones, aromatics, and glycol-based ethers are useful for epoxy resin dissolution. Protic solvents may not always be advisable, due to the possible side reaction of a proton-donating solvent molecule with the epoxide group of the resin monomer. Since most amine-based curing agents and accelerators are polar molecules, the aforementioned solvents could be appropriate for these components. Stearates or fatty acids are also polar since they contain the carboxylate ion. Many of the organotitanates and organozirconates can vary in solubility with particular solvents. The pyrophosphato-, phosphato-, and phosphito-functional titanates/zirconates, due to their aprotic polarity, have very good solubility in the following solvents: isopropanol, xylene, toluene, dioctyl phthalate and ketones. Other coupling agents of different functionality may have limited solubility in most conventional solvents. When using the recommended components in this invention, acetone has proven to be a very acceptable carrier fluid, for both coupled and non-coupled systems, because of its ability to dissolve the ingredients well and high vapor pressure at ambient temperature. Various embodiments of the invention contain and/or require a proper mixing procedure in order to obtain optimal characteristics. In the first embodiment of the present invention, the RE-TM-B magnet powders are coated with a homogeneous solution of the epichlorohydrin/cresol novoiac epoxy resin, a dicyandiamide curing agent, a tertiary amine accelerator and zinc stearate lubricating agent in acetone. Once added to the organics solution, mixing of the RE-TM-B magnet powders continues while the mixture is heated above room temperature for solvent removal. In the second embodiment of the present invention, a coupling agent is incorporated with the RE-TM-B magnet powders through a precoating process. An organotitanate-acetone solution is added to the magnetic powders and stirred followed by the subsequent evaporation of acetone. The pretreated RE-TM-B powders are then subjected to the mixing procedure as in the first embodiment that includes the epoxy system organic components. In the third embodiment of the present invention, the organotitanate coupling agent is incorporated with the RE-TM-B magnet powders and the epoxy system organic components through an admixing process. The RE-TM-B magnet powders are blended with a homogeneous acetone solution of the epichlorohydrin/cresol novolac epoxy resin, a dicyandiamide curing agent, a tertiary amine accelerator, zinc stearate lubricating agent, and the coupling agent. The relative amounts of the resin, curing agent, accelerator and lubricant are reduced accordingly in order to maintain an RE-TM-B powder mass percent of 98.3% when incorporating the coupling agent Figure 2 shows a plot of the flux aging loss results for cured magnets according to the first, second and third embodiments of the present invention. As can be seen in Figure 2, the magnetic material according to the second embodiment (Precoated CA) exhibits improved properties over the magnetic material of the first embodiment (No CA) due to the incorporation of the coupling agent (CA) through precoating the magnet powders. Furthermore, an enhancement of the flux aging loss of the RE-TM-B powders is attained when the organotitanate is admixed with the epoxy system components, as seen in Figure 2 for the third embodiment (Admixed CA). The magnetic material according to the fourth embodiment of the present invention has a similar formulation to the magnetic material of the third embodiment, but differs due to the addition of bentonite clay powder that has been chemically treated to contain bis (hydroxyethyl) methyl tallow alkyl ammonium salts within the admixing acetone solution. The relative amounts of the resin, curing agent, accelerator and lubricant are reduced accordingly in order to maintain a magnetic powder weight percent of 97.6% when incorporating the organoclays. Figure 3 shows a plot of the flux aging loss results for cured magnets according to the first and fourth embodiments of the invention. The incorporation of the additive of the treated bentonite clay powder within the admixing acetone solution results in a significant improvement in the flux loss of the magnetic material according to the fourth embodiment as compared to the first embodiment The magnetic material according to the fifth embodiment of the present invention has a similar formulation to the magnetic material of the fourth embodiment, but differs due to the initial precoating of a silanol-POSS with phenyl group functionality on the magnetic powders. A POSS-tetrahydrofuran (THF) solution is added and then stirred with the magnetic powders, followed by the evaporation of the THF solvent The pretreated powders are then subjected to the mixing procedure in the fourth embodiment with admixing the organics-acetone solution. The relative amounts of the resin, curing agent, accelerator and lubricant are reduced accordingly in order to maintain a magnetic powder weight percent of 97.6% when incorporating the organoclays. Figure 4 shows the improved flux aging loss results for cured magnets according to the fifth embodiment as compared to the cured magnets of the first and third embodiments.
