Abstract
PURPOSE: To smooth an anodic oxidation film and improve its slippery characteristic and abrasion resistance by forming the anodic oxidation film of aluminum then subjecting the same to secondary electrolysis treatment with a thio acid salt soln. of metals, and further grinding the film surface layer thereof.
CONSTITUTION: Aluminum or aluminum alloy is electrolyzed in an acidic or alkaline bath, whereby a porous alumite film is formed. Thence, if necessary, it is subjected to pretreatment, after which it is subjected to secondary electrolysis treatment by using a soln. of salts of thio acids of metals such as thiomolybdic acid and controlling its pH to around 4W12, whereby metal sulfide is densely impregnated in the micropores of the film. The surface layer of this film is ground to have a smoothed surface, and the metal sulfide is modified by the heat evolved during this grinding. This grid ing. The grinding methods include, for example, liquid honding, buffing and the like, and at least about 3μ is ground from the surface.
