| Title of Invention | ZINC PHOSPHATE TREATMENT LIQUID COMPOSITION FREE FROM GENERATION OF SLUDGE AND ZINC PHOSPHATE TREATMENT METHOD |
|---|---|
| Abstract | A Zinc phosphate treatment liquid, wherein the molar concentration [mol/L]of H3PO4,HNO3 and Zn satisfy the relation of the following formula[Zn]< 0.3[H3PO4]+0.5[HNO3]. This zinc phosphate treatment liquide may contain preferably additives. selected from nitrous acid, permanganic acid, persulphuric acid, hydrogen peroxide, chloric acid, perchloric acid, nitrobenzene sulfonic acid, hydroxylamine, starch phosphate ester, fluorine compounds and salts therrof. The metallic material is treated by means of cathode electrolytic process in zinc phosphate treatment liquide of above. The metallic material may be contacted with a colloidal solution containing titanium oxide, titanium hydroxide and zinc phosphate prior to teh cathodic electrolysis process. |
