Abstract

See full text

Disclosed is a sliding member having an overlay layer (13) containing Bi-based particles (14) comprising Bi or a Bi alloy. The long axis of the Bi-based particles (14) is considered to be X, the short axis Y, and the aspect ratio Z=X÷Y. The aforementioned Bi-based particles are classified as one of either first Bi-based particles that satisfy Z<2, second Bi-based particles that satisfy 2≦Z<3, or third Bi-based particles that satisfy 3≦Z. With respect to the total number of Bi-based particles, considering the proportion that are first Bi-based particles to be a%, the proportion that are second Bi-based particles to be b%, the proportion that are third Bi-based particles to be c%, a÷b=d, and a÷c=e, the sliding member satisfies: a≧30, 0.5≦d≦6.0, and 0.5≦e≦6.0.
