Abstract: In a slide member in which an overlay is provided on a slide receiving surface of a base member, the overlay is formed by attaching a mixed solid lubricant on the slide receiving surface of the base member. The mixed solid lubricant is made by mixing a large amount of hydrogen containing solid lubricant which contains a large amount of hydrogen, and a small amount of hydrogen containing solid lubricant which contains a smaller hydrogen amount than the large amount of hydrogen containing lubricant. Thereby, a lubricant absence region where the solid lubricant is absent in a thickness direction is formed on the slide receiving surface of the base member after sliding, and an oxidized portion where the base member is oxidized is formed in the lubricant absence region.

Abstract: A multilayer aluminum-base alloy bearing formed by bonding a bearing alloy layer made of an aluminum-base alloy to a steel back metal through an intermediate layer made of an aluminum-base alloy, the intermediate layer being composed of two layers, that is, a lower layer and an upper layer, the lower layer in contact with the steel back metal being lower in hardness than the upper layer. Since the lower layer is soft, it is excellent in bonding property for the back metal, and since the upper layer is hard, it withstands a load exerted on the bearing alloy layer.
