ABSTRACT:
A process is described for the production of bearings for sustaining high loads, the bearings having indentations filled with soft overlay alloy. The indentations are produced by peening or embossing. The peening is preferably performed with rounded ceramic shot of 0.25 to 0.5 mm diameter. Indentations should preferably be between 0.01 and 0.05 mm deep. In one embodiment a bearing is described having alloy comprising a steel-backed aluminium-based bearing alloy having a composition of, for example, Al-Sn2O-Cul and a soft Pb-Sn10 overlay there also being an interlayer of 3 to 5 .mu.m of nickel between the bearing alloy and the overlay. Bearing surfaces having a continuous overlay or a composite surface comprising randomly-shaped areas of bearing alloy and overlay may be produced.
