<P>PROBLEM TO BE SOLVED: To provide a swash plate compressor improved in abrasion resistance and slidability of a swash plate and shoes, and a surface treatment method for the swash plate in the swash plate compressor. <P>SOLUTION: A variable-capacity swash plate compressor comprises: a shaft passing through a crank chamber and rotatably supported at a housing; a swash plate 22 that includes an opening through which the shaft is inserted, is disposed in the crank chamber and rotates synchronously with rotation of the shaft; pistons, each held at a circumferential edge of the swash plate 22, which slides reciprocally in a cylinder bore as the swash plate 22 rotates; and shoes 24, disposed between two side surfaces of the swash plate 22 and an engaging portion of the piston, which slide in contact with both the swash plate 22 and the piston. The swash plate 22 is constituted of an iron-based material. The sliding contact surfaces 34 of the swash plate 22 against the 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 formed hardened layer 36, and a coating process 37 executed after the removal process to form a coating constituted of a solid lubricant. <P>COPYRIGHT: (C)2012,JPO&INPIT |
