OXIDIZED FILM STRUCTURE OF IODINE OR IODINE COMPOUND- IMPREGNATED METALLIC MATERIAL BASE MATERIAL, ITS FORMATION, AND APPLIED ARTICLE HAVING THE FILM STRUCTURE

摘要

PROBLEM TO BE SOLVED: To obtain a metallic material excellent in wear resistance, antibacterial properties, bactericidal properties, photo-environmental catalytic property, coloring property or the like by forming an oxidized film on the surface of a base material of a metallic material of Al, Mg, Ti, Cu or the like and impregnating the fine pores or fine ruggedness of this film with iodine or an iodine compd. SOLUTION: The surface of a base material of a metallic material composed of Mg, Ti, Zr, Hf, V, Ta, Cr, Mo, W, Mn, Fe, Ru, Os, Rh, Ni, Cu, Zn, Al, Pb, the allays thereof or the like, is previously roughened, e.g. by physical, chemical or electrochemical means, and, thereafter, by anodic oxidation or chemical treating oxidation, an oxidized film is formed. Next, the fine poers or fine ruggedness of the oxidized film in this base material is impregnated with iodine or an iodine compd. As this iodine compd., the one obd. by combining an organic compd. or metal with a characteristic group of iodine is used. Moreover, the impregnation of iodine or the like is executed preferably by electrophoretic deposition.
