Abstract: Provided is a plain bearing including a backing layer, a bearing metal layer, an optional intermediate layer and an overlay. The overlay includes a plurality of sub-layers disposed one on top of the other, which sub-layers include two or more relatively soft sub-layers and one or more relatively hard sub-layer. The soft and hard sub-layers are arranged alternately with respect to one another. Each soft sub-layer includes a metal or metal alloy, and each hard sub-layer includes one or more intermetallic compound.A method of making a coated plain bearing is also provided.

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%.
