摘要
Sliding parts are made of Pb-free Cu-Bi based sintered material. The side in contact with a shaft is machined to a predetermined roughness. A number of Bi phases are present on the finished surface. Stable performance of Bi is to be exhibited. Machined sintered material covers a portion of the Bi phases. The ratio of the exposed surface area of the Bi phases is 0.5% or more relative to the area of the finished surface.
