Abstract
Under wet sliding conditions using drivetrain system lubricating oils, a high frictional sliding member exhibiting a high friction coefficient, a favorable μ−v characteristic stably, excellent wear resistance, and low mating-member aggressiveness is provided. The present invention is a wet sliding member comprising: a substrate composed of metal, ceramics, or resin; and an amorphous hard carbon film formed integrally on a surface of the substrate, having a surface, at least a part of which is turned into a sliding surface for sliding under wet conditions, and containing at least either one of Si and N in an amount of from 1 to 50 atomic %.
