ABSTRACT:
A first member is configured to undergo sliding contact with a surface of a second member. The surface of the first member is roughened by irradiating the surface of the first member with a laser to form first recesses in the surface of the first member. The surface of the first member is then cleaned followed by a finely roughening step of irradiating the first recesses formed in the surface of the first member with a plasma to form second recesses which are shallower than the first recesses. Thereafter, a fluorocarbon resin is coated on the surface of the first member so that the fluorocarbon resin securely contacts and adheres to the surface of the first member due to the rough and clean state thereof. The surface of the first member is then subjected to a heat treatment.
