Abstract
A multilayer sliding material which is used, in particular, as the material of the bearings in internal combustion engines, comprising a steel backing layer, a bearing layer of copper-based alloy bonded to the steel backing layer, a silver or silver alloy plating layer bonded to the bearing layer, and a surface layer of lead-based alloy bonded to the silver or silver alloy plating layer, the silver or silver alloy plating layer having a thickness of more than 3 microns but not more than 50 microns. The multilayer sliding material having a thick plating layer of silver or silver alloy, excels in seizure-resisting.
