Abstract
An object of the present invention is to provide a sliding member suitable to a soft mating member low in hardness. The present invention relates to a sliding member for sliding with a mating member having a ferrite phase at least on a surface thereof, the sliding member including a coating layer containing a binder resin, molybdenum disulfide, and hard substance particles.
Claims3
A sliding member for sliding with a mating member having a ferrite phase at least on a surface thereof, the sliding member comprising:
- a coating layer comprising a binder resin, molybdenum disulfide, and hard substance particles which have an average particle diameter that is 0.5 to 10 times as large as a surface arithmetic average roughness Ra of a sliding surface of the mating member,
- wherein the hard substance particles have a massive form, and
- wherein the massive form is an irregular form that does not substantially contain projections equal to or smaller than 90°, and excludes forms such as spherical and acute angle forms that can be formed by processing.
A sliding material composition for use in a sliding member for sliding with a mating member having a ferrite phase at least on a surface thereof, the sliding material composition comprising:
- a binder resin;
- molybdenum disulfide;
- and
- hard substance particles which have an average particle diameter that is 0.5 to 10 times as large as a surface arithmetic average roughness Ra of a sliding surface of the mating member,
- wherein the hard substance particles have a massive form, and
- wherein the massive form is an irregular form that does not substantially contain projections equal to or smaller than 90°, and excludes forms such as spherical and acute angle forms that can be formed by processing.
