SLIDING RESIN COMPOSITION, AND SLIDING MEMBER

摘要

A resin composition used for a sliding member to improve seizing resistance. The sliding resin composition includes: a resin binder; a solid lubricant; and aggregates of particles. A coupling force between the particles in the aggregates is smaller than a threshold stress of the resin binder so that the aggregates exposed at a surface of the resin binder are partially detached with a force smaller than the threshold stress of the resin binder. The aggregates of the particles harder than the resin binder are used as a protecting and reinforcing agent, and the amount of the particles contained in the sliding resin composition is 1 vol. % or more but 20 vol. % or less of the entire sliding resin composition. The particles harder than the resin binder have an average particle diameter of between 10 nm and 100 nm that is smaller than that of the solid lubricant.
