Abstract
The bearing is composed of a strong metallic backing, a softer metallic support layer, and a galvanically applied metallic anti-friction layer, the support layer and the anti-friction layer being of mutually different metals or metallic alloys. An intermediate layer is provided between the support layer and the anti-friction layer. The intermediate layer is made as a layer which prevents or limits diffusion of metallic components from the anti-friction layer into the supporting layer and vice versa, and is composed of a binding layer, entering into a lasting surface bond with the material of the anti-friction layer, and of an underlayer, entering into a lasting surface bond with the material of the support layer.
