ABSTRACT:
An electro-composite tribological coating for coating a flexible or compliant structure, for example a structural seal, includes a cobalt and cobalt alloy base containing a fine dispersion of tribologically suitable particles such as chromium carbide (Cr3C2), silicon carbide (SiC), carbon graphite, and the like, which can be deposited directly on the outer surface of the seal as a near-net shape coating requiring little or no mechanical polishing or grinding. The coating is deposited on the seal in one embodiment by an electrolytic bath. In this manner, a near-net shape coating of a desirable thickness, for example having a thickness of about 0.005″ and a desirable surface finish can be achieved in the as-plated condition with little or no additional polishing or grinding after coating.
