SLIDE MEMBER INCLUDING DIAMOND-LIKE-CARBON (DLC) FILM

摘要

PROBLEM TO BE SOLVED: To provide a slide member improved in wear resistance and highly reliable over a long period by improving the adhesion property (anti-flaking property) of a diamond-like-carbon coating film to shearing in the slide member including the diamond-like-carbon coating film.;SOLUTION: The sliding member includes a substrate and the DLC film, including a first layer, arranged on the substrate, wherein the substrate is formed of an alloy steel containing at least one element selected from the group consisting of V, Cr, Nb, Mo, Ta and W, the first layer contains at least one element selected from the group consisting of V, Cr, Nb, Mo, Ta and W, and the same crystal structure continues from the substrate toward the first layer.;COPYRIGHT: (C)2013,JPO&INPIT
