Abstract: Provided is a slide member having an overlay on a bearing alloy. The overlay has a thickness T and has a sliding surface and an interface with respect to the bearing alloy. The overlay includes an intermetallic compound and a matrix of Bi or a Bi alloy. In a thickness domain constituting 70%-75% of the thickness T of the overlay from the sliding surface to the interface, the volume proportion of the intermetallic compound is 10%-70%.

Abstract: A sliding member of the present embodiment includes: a lining layer including a Bi phase; and a coating layer containing Ni, the coating layer being provided on a surface of the lining layer, the coating layer partially forming an entrance portion that has entered the lining layer side at an interface with respect to the lining layer. At any observation region including the interface between the lining layer and the coating layer, a value R=S1/S2 of a ratio of a maximum area S1 of the Bi phase included in the lining layer to a maximum area S2 of the entrance portion that has entered the lining layer is 1.00≤R≤9.00.

Abstract: In a sliding member, fatigue resistance of a surface layer formed by dispersing a hard material in a soft metal matrix is improved. A sliding member includes a base material layer and a surface layer, the surface layer includes a metal matrix and a hard material harder than the matrix and dispersed in the matrix, the hard material has a gradient in hardness, and the gradient in hardness gradually decreases from an inner side to a surface of the hard material.
