ABSTRACT:
A method of applying solid lubricant to a bearing with rolling surfaces which comprises the steps of sputter cleaning the bearing substrate and implanting ions of the solid lubricant to a shallow depth in the surface of the substrate to improve the bonding of the solid lubricant plating which is subsequently deposited by plasma-assisted ion plating in a thin layer of approximately 1000 .ANG. directly over the implanted substrate and wherein the plating is applied to the bearing substrate at high temperature and in the presence of low pressure inert gas ions to improve surface structure and wherein the bearing element is then cooled in a vacuum.
