LAMINATE FOR PLAIN BEARINGS WITH LEAD-FREE BEARING SURFACE

摘要

A composite plain bearing material has an electroplated sliding layer of a tin-copper-cobalt alloy. A composite plain bearing material consists of a backing layer, a bearing metal layer of a copper alloy (50-95 wt.% Cu) or an aluminum alloy (60-95 wt.% Al), a diffusion barrier layer and an electroplated sliding layer of a lead-free tin-copper alloy which contains 8-30 wt.% Cu, 60-97 wt.% Sn and 0.5-10 wt.% Co.
