Abstract
A laminated material for a plain bearing includes a running layer characterized by a high degree of hardness and good embedding and adaptation properties and high corrosion resistance. The laminated material is provided with a bearing material applied by sputtering directly to a carrier material, the bearing material comprising a matrix material of copper or copper base alloy with finely divided lead inclusions. The matrix material is isotropically crystallized with polygonal grain shape. The mean crystallite diameter is 2-4 .mu.m and the grain size of the lead inclusions is 0.2-0.4 that of the crystallite diameter.
Claims18
A multilayer bearing material comprising a metallic backing layer, and a metallic functional layer applied by sputtering directly to said backing layer, said functional layer including a matrix of copper-based material having inclusions of lead dispersed therein, said copper-based matrix material being isotropically crystallized and having a polygonal grain shape with an average crystallite grain diameter of about 2-4 .mu.m, said lead inclusions having an average grain diameter that is about 0.2 to 0.4 times that of the crystallite diameter.
