Abstract

A swash plate type compressor is arranged with a plurality of semispherical shoes and a disc shaped swash plate. A resin coating is formed on a surface and a rear surface (sliding surface) of the swash plate which slides with the shoe. The resin coating includes a structure whereby multiple hexagonal cylinder bodies are fabricated on a surface of a substrate and an end surface of each cylinder body forms a sliding surface which slides with the shoe. In addition, a honeycomb shaped groove is formed at an adjacent position of each cylinder body forming a storage part of a lubricant O and a container part for foreign objects.
The swash plate can be provided with excellent wear resistance, seizure resistance and lubrication retention.

First claim

What is claimed is:

1. A sliding component comprising:
a base; and
a coating layer formed on a surface of the base, the coating layer forming a sliding surface which slides with a movable component comprising:
wherein
the coating layer is formed from a resin coating having a structure wherein multiple hexagonal cylinder shaped bodies or multiple triangular cylinder shaped bodies are fabricated on a surface of the base;
the sliding surface is formed by an end surface of an opposite base side of each of the cylinder bodies;
a honeycomb shaped groove is formed from spaces between adjacent cylinder bodies; and
the interior of the honeycomb shaped groove acts as a storage part for lubrication and a container part for containing foreign objects.

2. The sliding component according to claim 1 , wherein the sliding component is a swash plate of a swash plate type compressor, a thrust washer or a thrust bearing.

3. The sliding component according to claim 1 , wherein a material of the resin coating is comprised from a thermoset resin including a solid lubricant and/or hard particles wherein one or more material selected from MoS2, graphite, WS2, h-BN, fluororesin, CF is used as the solid lubricant, one or more material selected from an oxide, nitride, carbide, sulfide is used as the hard particles and one or more material selected from PAI, PI is used as the thermoset resin.
