Abstract
PURPOSE: To impart superior lubricity to an aluminum alloy by containing metals that create lubricative sulfide to the aluminum alloy and anodizing the same thence subjecting the same to secondary electrolysis treatment with a metallic salt soln. of thio-acid.
CONSTITUTION: At least one or more kinds of about 0.1W20wt% if, for example, Mo, W, and about 8W25wt% if Pb, Sn are contained in an aluminum alloy, and the maximum thereof is kept ≤about 30wt%. Thence, it is anodized in an acidic bath, alkali bath or nonaqueous bath, whereby a porous film is formed on the aluminum. After this, if necessary, it is subjected to pretreatment, to active the film, thence it is subjected to secondary electrolysis. The secondary electrolysis is accomplished with ammonium salts etc. of thiomolybdic acid, thiostannic acid, etc., and the pH is controlled to around 4W12. The material to be treated is made plus. Thereby, metal sulfide is formed and fixed in the micropores of the film and on the surface of walls.
