Abstract: A sliding member includes a bearing alloy layer, a solid lubricant layer, particles and a covering portion. The solid lubricant layer is provided on a sliding surface side of the bearing alloy layer and is deposited on the bearing alloy layer. The particles form the solid lubricant layer and are made of metal sulfide. The covering portion is provided over outermost surfaces of the particles on the sliding surface side and are made of metal oxide including the same metal element as a metal element constituting the particles.

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.

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%.
