Problems solved by technology

[0006] Under the above-mentioned harsh sliding conditions, in the case where the film application length of the solid lubricating coating film is increased to improve the wear resistance of the sliding surface, the running-in performance of the sliding surface is reduced, thereby increasing its sliding resistance, so that the applied The film is peeled off, which reduces the anti-adhesion and seizure of the sliding surface

Embodiment 1

[0054] By thermal spraying a thermal spraying material including Cu44.0%, Sn2.0%, Pb9.0%, Al25.0% and Si20.0% to a base for a swash plate formed of an iron-based material On the piece, an intermediate layer is formed. Then, as a solid solution film compound, raw materials were prepared in such a manner that it included 50% by mass of polyamide-imide resin, 24% by mass of PTFE (average particle diameter 5um) and 20% by mass of graphite (average particle diameter 1um). N-methyl-2-pyrrolidone, which is a solvent for the resin, is added to the raw materials, and they are mixed together, and the mixture is applied to the substrate on which the intermediate layer is formed by spraying, thus forming a film having a thickness of 40 μm. solid lubricant coating. After that, the solid lubricating coating was burnt at a temperature of 190° C. for one hour, and then the solid lubricating coating thus burned was placed on a lathe using a diamond blade of 0.8 R (curvature) at a feed speed ...

Abstract

It is an object of the invention to provide a slide member which is excellent in the initial running-in property and can provide an excellent sliding property even under a strict sliding condition and, in particular, a slide member with a solid lubrication coating film which is excellent not only in the friction property but also in the wear resistance under the fluid lubrication, boundary lubrication and dry lubrication conditions. The invention provides a slide member which includes a solid lubrication coating film on a flat-plate-shaped base member, characterized in that, in the surface of the slide member, there are formed a plurality of concentrical grooves extending in the peripheral direction of the slide member surface, and, between the mutually adjoining ones of the grooves, there are formed ridge portions respectively.

Description

technical field [0001] The present invention relates to a flat plate-shaped sliding member such as a swash plate of a compressor, more particularly, the present invention relates to a circular plate-shaped sliding member, and more particularly, the present invention relates to a sliding member having a solid lubricating coating film, The coating film not only improves the initial running-in performance, but also improves the friction characteristics in the case of fluid lubrication. Background technique [0002] Conventionally, among various sliding members, there is a widely known technique of applying a solid lubricating coating film to a sliding surface of a sliding member, thereby improving boundary lubrication performance and drying performance. [0003] Especially, in the impact cam type compressor, the compressor includes: a swash plate fixed obliquely to the rotating shaft, or the swash plate is fixed obliquely to the rotating shaft in such a manner that its inclinat...
