DLC FILM DEPOSITION METHOD, AND DLC COATED ALUMINUM ALLOY AND DLC COATED MAGNESIUM ALLOY USING THE METHOD

摘要

PROBLEM TO BE SOLVED: To improve the sliding characteristics of machine parts made of aluminum alloy and machine parts made of magnesium alloy and to thereby promote the utilization of aluminum alloys and magnesium alloys in various fields of technology. SOLUTION: In the DLC(diamond-like carbon) film deposition method for depositing a DLC film on the surface of a substrate, solution heat treatment is applied to the substrate and then aging treatment and DLC coating treatment are simultaneously carried out by a combined simultaneous treatment process.
