Title: Pretreatment of valve metal before anodic oxidation
Inventor: YAMAGUCHI HIDETOSHI
IPC: C25D11/26
Filed: 1987-04-02
Abstract: PURPOSE:To prevent uneven coloring by anodic oxidation and to develop uniform vivid colors by successively treating a valve metal with dil. sulfuric acid and dil. hydrofluoric acid and pickling the metal so as to pretreat the metal before anodic oxidation. CONSTITUTION:A valve metal having coarse grains such as Ti or a Ti alloy is treated with dil. sulfuric acid having >=20wt.% concn. at 50-200 deg.C to etch the grain boundaries. By this etching, a very small amt. of impurities present on the grain boundaries is preferentially dissolved and the boundaries are made distinct. The metal is further treated with dil. hydrofluoric acid having >=2% concn. to further etch the grain boundaries and sulfide smut produced on the surface of the metal is washed off. The metal is then pickled to clean and activate the surface. By the above-mentioned pretreatment, a fancy colored valve metal is obtd. after anodic oxidation.
