(54) Swash plate for compressor


(57) The swash plate (10) of a compressor is coated on both surfaces, the skirt side contact surface (30A) receives the skirt side shoes (20A), and the opposite head side contact surface (30B) receives the head side shoes (20B). The coating applied on the skirt side contact surface is molybdenum disulphide, tungsten disulphide, graphite, boron nitride, antimony oxide, lead oxide, indium, tin or fluorocarbon resin applied by spray coating, roll coating or screen printing processes. The coating applied on the head side contact surface consists of two layers. The first layer (31B-1) consists of aluminium silicon alloy. The second layer (31B-2) applied on the first layer consists of a solid lubricant similar to the coating of the skirt side contact surface. Additionally, the head side contact surface may be roughened by shot blasting.
