Abstract
In a composite material for sliding surface bearings, a rough metallic surface is provided with a polymeric matrix, which forms a friction contact or sliding layer over the rough base surface. To increase the wear resistance, the matrix contains zinc sulfide and/or barium sulfate in a particle size from 0.1 to 1.0 .mu.m and an average particle size of 0.3 .mu.m.
Claims25
A composite material for sliding surface bearings, comprising a polymeric matrix bonded to a metallic rough base surface to form a polymeric friction contact or sliding layer in a thickness from 0.01 to 2.0 mm over the peaks of the rough base surface, wherein the matrix comprises 5 to 50% by volume of barium sulfate particles, said particles having a particle size from 0.1 to 1.0 .mu.m and an average particle size of 0.3 .mu.m
