Abstract

The invention discloses an automotive air-conditioning compressor swash plate part. The swash plate part is in the shape of a ring and comprises a front sway arranged on the inner side of the ring and a collar arranged on the outer edge of the ring, a swash plate is integrally formed in an iron-based manner, each of the upper side and the lower side of the collar is deposited with a high-nickel-phosphorus compound alloy layer, with nickel as a main component, and the high-nickel-phosphorus compound alloy layer contains 10-12% of phosphorus, and is doped with 1-3% of crystal whiskers and inevitable impurities. The automotive air-conditioning compressor swash plate part integrally cast is high in strength and low in cost, the surfaces of the swash plate collar are disposed with the nickel-phosphorus alloy layer doped with potassium titanate whiskers doped from a chemical nickel-plating solution, so that wear resistance is better, and service life of a compressor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobile air-conditioning compressors, and in particular relates to the wear resistance of swash plate components. Background technique [0002] With the development of the automobile manufacturing industry, the research on automobile air conditioning technology is getting faster and faster. The automotive air-conditioning compressor is the core component. The automotive air-conditioning compressor usually uses a swash plate rotary piston for compression. The high-speed rotation of the swash plate can reach 3000 rpm, so the requirements for wear resistance are very high. At present, the swash plate in air-conditioning compressors usually adopts a split type, that is, the part in the middle of the swash plate that is driven by a motor to rotate is made of cast iron or stainless steel, while the ring shoulder on the outer circumference of the swash plate (friction with other parts due to high-speed rotati...
