ABSTRACT:
A Cu skin film is formed of an aggregate of Cu crystals. Pyramid-shaped Cu crystals and/or conical Cu crystals exist in the surface of the Cu skin film. The area rate A of the pyramid-shaped Cu crystals, the area rate A of the conical Cu crystals or the sum A of the area rates of these Cu crystals in the skin film surface are set in a range of A.gtoreq.40%. The skin film surface takes on an intricate aspect due to the existence of the infinite number of pyramid-shaped Cu crystals and/or conical Cu crystals. If such a Cu skin film is formed, for example, on a surface opposite from that surface of a backing of a slide bearing which is opposed to a rotary shaft, the Cu skin film exhibits a good oil retention and therefore seizure due to a fretting can be avoided.
