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.
Claims19
A multilayer aluminum-base alloy slide member formed by bonding a slide alloy layer made of an aluminum-base alloy to a back metal layer through an intermediate layer made of an aluminum-base alloy, the intermediate layer being composed of a layer in contact with the back metal layer and at least one layer disposed toward the slide alloy layer from the layer in contact with the back metal layer, and at least one of those layers, which are disposed toward the slide alloy layer from the layer in contact with the back metal layer, being higher in hardness than the layer in contact with the back metal layer.
