Abstract

A variable-capacity swash plate compressor (1) comprising a shaft (9) passing through a crank chamber (8) and rotatably supported at a housing (7), a swash plate (22) that includes an opening through which the shaft (9) is inserted, is disposed in the crank chamber (8) and rotates synchronously with rotation of the shaft (9), pistons (18), each held at a circumferential edge of the swash plate (22), which slides reciprocally in a cylinder bore (17) as the swash plate (22) rotates, and shoes (24), disposed between one of the two side surfaces of the swash plate (22) and an engaging portion of the piston (18) which slides in contact against both the swash plate (22) and the piston (18).
The swash plate (22) is constituted of an iron-based material.
The sliding contact surfaces of the swash plate (22) that slide in contact against shoes (24) undergo a gas soft-nitriding process, a removal process executed after the soft-nitriding process in order to remove a nitride-containing compound layer while retaining a hardened layer having been formed through the soft-nitriding process, and a coating process executed after the removal process to form a coating constituted of a solid lubricant.
