Abstract
A bearing includes a liquid lubricant and at least one ceramic component, which, during operation of the bearing, is subject to rolling contact load. A tribological surface of the at least one ceramic component is impregnated with a sealant, such that the liquid lubricant is prevented from entering discontinuities in the tribological surface.
Claims9
A bearing comprising:
- a liquid lubricant, and
- at least one ceramic component which, during operation of the bearing, is subject to a rolling contact load, wherein
- a tribological surface of the at least one ceramic component is impregnated with a sealant, such that the liquid lubricant is prevented from entering discontinuities in the tribological surface, wherein the sealant comprises an oil-repellent material.
A method of inhibiting crack propagation in a component of a bearing that is subject to fatigue loading, the bearing component having a tribological surface which, in operational use of the bearing, is wetted by a lubricant, wherein,
- the method comprises a step of impregnating the tribological surface with a sealant comprising an oil-repellent material such that discontinuities in the tribological surface are sealed to prevent ingress of the lubricant.
