Abstract
To provide a technique capable of realizing an appropriate wear resistance in a resin coating layer. The sliding member of the present invention is a sliding member including a base layer and a resin coating layer formed on the base layer, wherein the resin coating layer is formed of a polyamide-imide resin as a binder, barium sulfate particles, molybdenum disulfide particles, and unavoidable impurities, wherein the resin coating layer is composed of a plurality of overcoated application layers, and wherein the plurality of application layers are different from each other in content of hard particles.
Claims2
A sliding member comprising a base layer and a resin coating layer formed on the base layer,
- wherein the resin coating layer comprising:
- a polyamide-imide resin as a binder;
- barium sulfate particles;
- molybdenum disulfide particles;
- and
- SiC particles as hard particles,
- wherein the resin coating layer is composed of an outermost layer and an inner layer, which are two overcoated application layers,
- wherein the SiC particles are blended in the outermost layer and the inner layer, and wherein the content of the SiC particles in the inner layer is 0.3 vol. % to 1.5 vol. %;
- and,
- wherein a content of the SiC particles in the outermost layer is lower than a content of the SiC particles in the inner layer.
