    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 %.

    Abstract: A low-friction sliding member is used under a wet condition employing a lubricant, and includes a substrate having a surface, and an amorphous hard carbon film formed on the surface of the substrate for contacting slidably with a mating member. The amorphous hard carbon film includes silicon in an amount of from 1 atomic % or more to 20 atomic % or less, hydrogen in an amount of from 20 atomic % or more to 50 atomic % or less, and the balance of carbon and inevitable impurities, when the entirety is taken as 100 atomic %, and exhibits a surface roughness Rzjis of 0.8 μm or less. The low-friction sliding member exhibits reduced friction coefficients between itself and mating members, without relying on the adsorption and reaction of additives, included in lubricants, to the amorphous hard carbon films.
