Abstract
A bearing including a backing formed of a steel material, a lining formed of aluminum or an aluminum alloy, and a diffusion barrier layer 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.
Claims20
A bearing comprising:
- a backing formed of a steel material,
- a lining disposed along said backing, said lining being formed of aluminum or an aluminum alloy,
- a diffusion barrier layer disposed between said backing and said lining, said diffusion barrier layer being formed of nickel or a nickel alloy, and said diffusion barrier layer having a thickness ranging from 1 micron to 100 microns.
A method of manufacturing a bearing, comprising the steps of:
- obtaining a bearing including a backing formed of a steel material, a lining formed of aluminum or an aluminum alloy disposed along the backing, and a diffusion barrier layer being formed of nickel or a nickel alloy disposed between the backing and the lining;
- and
- heating the bearing.
A method of manufacturing a bearing, comprising the steps of:
- disposing a lining formed of aluminum or an aluminum alloy along a diffusion barrier layer, the diffusion barrier layer being formed of nickel or a nickel alloy;
- and
- disposing the diffusion barrier layer along a backing formed of a steel material.
