Method of coating fluorocarbon resin, and sliding member and gas compressor using the same

摘要

A method of coating a fluorocarbon resin includes roughening a coating surface by shot-blasting using a water-soluble shot material or a vaporizable shot material or by irradiation of laser or plasma. The method provides a high-quality fluorocarbon resin coating having excellent contact and adhesion properties, which is not peeled off even during a sliding movement performed under severe load conditions. In addition, a shot material used in the coating substrate treatment does not remain in a base material made of an aluminum alloy or the like in the vicinity of a coating layer. Thus, there is no possibility that residual shot material damages the coating layer or the like.
