摘要:
A multi-layer bearing consists of a backing steel plate, a layer of Cu--Pb bearing alloy comprising, by weight, 1 to 20% of Ni and containing Pb-phase grains dispersed in the matrix, and an overlay of Pb alloy containing In. In in the overlay is diffused into the Pb-phase grains in the bearing alloy layer and forms a diffusion layer of high corrosion resistance in which In coexists with the Pb-phase grains, in an area of 30 to 200 .mu.m from the interface to the overlay. Even if the overlay is worn and the Cu--Pb bearing alloy layer is exposed, high corrosion resistance will be maintained.
