ABSTRACT:
A method of eliminating scrubbing noise between metal to metal (or metal to ceramic) contact members that experience articulating swiveling interengagement at high force levels in excess of 5,000 psi. The method comprises: (a) preparing the interface to present at least one fresh mechanically adherable stiff surface; (b) thermally spraying a top coating thereonto consisting of at least one of (i) a self-lubricating metal, ceramic material or metal alloy, and (ii) a compliant metal; and (c) placing the coating interface into service to subject it to repeating articulating swiveling contact that functions to microweld the coating to the surface under normal operating conditions.
