Abstract
A rough and porous coating is applied by spraying and metallurgically bonding to a bearing member. The coating is preferably of a strong and thermally conductive material, such as aluminum-bronze, with the coating having interstices, such as cavities, undercuts, and craters to provide a porous material. An adhesive-solid lubricant formulation is then applied to the coating. The adhesive-solid lubricant formulation fills the coating interstices. The adhesive-solid lubricant formulation is cured for the required time at the required temperature to form a low-friction bearing surface layer.
Claims12
A bearing element consisting of a bearing substrate having a low-friction slide surface layer, said layer comprising:
- a porous coating metallurgically spray-bonded to the substrate surface, and having interstices, such as craters and undercuts, and an adhesive-solid lubricant formulation applied over the coating, at least a portion of the adhesive-solid lubricant formulation at least partially filling the coating interstices.
A bearing comprising two bearing elements having surfaces in mating slidable engagement with each other, the surface of at least one of said elements comprising:
- a rough and porous coating metallurgically spray-bonded on said surface and having interstices;
- and an adhesive-solid lubricant formulation applied over the coating, at least a portion of the adhesive-solid lubricant formulation at least partially filling the coating interstices.
