BEARING AND METHOD OF MANUFACTURING PERMITTING HIGH TEMPERATURE HEAT TREATMENT

摘要

A bearing including a backing formed of a steel material, a lining formed of aluminum or an aluminum alloy, and a diffusion barrier layer (12) disposed between the backing and the lining is provided. The diffusion barrier layer is formed of nickel or a nickel alloy and has a thickness ranging from 1 micron to 100 microns. The bearing is typically formed by cladding the lining or plating the steel backing with the diffusion barrier layer, bonding the lining and the backing with the diffusion barrier layer between, heating to a temperature of at least 400° C, and forming the bearing into a shape after or before the heating step.
