METHOD OF TREATING ANODIC OXIDE FILM AND CATHODIC OXIDE FILM HAVING REDUCED ENVIRONMENTAL LOAD BY VIRTUE OF STAINLESS STEEL, AND SURFACE TREATMENT LIQUID

摘要

PROBLEM TO BE SOLVED: To provide an anodization method which can improve corrosion resistance of stainless steel, can protect stainless steel from stain and fingerprints and can reduce an environmental load.;SOLUTION: A solution made of an aqueous solution comprising sulfuric acid or phosphoric acid, nitric acid, oxalic acid, silicon, molybdenum or titanium oxide is used, a DC current is applied in the solution by using a body to be processed made of stainless steal serving as an anode and, thereby, a composite film is formed by impregnating a porous layer produced on the surface of the body to be processed with silicon and molybdenum or titanium oxide.;COPYRIGHT: (C)2010,JPO&INPIT
