Scroll parts, scroll compressors equipped with these scroll parts, and methods for manufacturing scroll parts

摘要

The scroll component has a sliding surface that slides with other members, and includes a scroll base material made of an aluminum alloy and a coating layer formed on the sliding surface of the scroll base material. The coating layer is formed on the sliding surface and is formed on the surface of the zinc phosphate layer containing zinc phosphate particles and the surface of the zinc phosphate layer, and is formed on the surface of the solid lubricating layer containing solid lubricant particles and the surface of the solid lubricating layer. It comprises a binder and a polishing layer containing abrasive particles having a Mohs hardness higher than the Mohs hardness of the binder.
