Abstract:
A contact member or a slide member of the present invention comprises a surface treatment film (160) including two or more coating layers stacked together, in at least a portion of a contact surface or a slide surface thereof, wherein each of the coating layers includes synthetic resin and a solid lubricant, and wherein the solid lubricant (162) of the coating layer located at an innermost side is lower in content percentage than the solid lubricant of the coating layer located at an outermost side. A contact member or a slide member of the present invention comprises a surface treatment film (160) including two or more coating layers stacked together, in at least a portion of a contact surface or a slide surface thereof, each of the coating layers includes synthetic resin, and the coating layer located at an innermost side is larger in elastic deformation amount than the coating layer located at an outermost side.
Abstract:
A slide member of the present invention is used in a slide unit which is included in a refrigerant compressor for compressing a refrigerant and provided inside a sealed container which reserves lubricating oil therein. The slide member is provided with an oxide coating film on a surface of a base material. The oxide coating film is configured such that (1) when the base material comprises an iron based material, the oxide coating film has a three-layer structure including a first layer comprising Fe2O3, a second layer comprising Fe3O4, and a third layer comprising FeO in this order from an outermost surface, (2) the oxide coating film has a dense structure having minute concave/convex portions with a height difference which falls within a range of 0.01 μm to 0.1 μm, or (3) when the base material comprises the iron based material, the oxide coating film has a three-layer structure in which the three layers comprise the iron oxides and are different in hardness.
