Piston Ring With A Wear-Resistant Cobalt Coating
US Patent:
2013011, May 9, 2013
Filed:
Nov 9, 2012
Appl. No.:
13/673546
Inventors:
Mitchell T. Marsh - Saline MI, US
Assignee:
Federal-Mogul Corporation - Southfield MI
International Classification:
F16J 9/26, C25D 7/04
US Classification:
277442, 205122, 205151
Abstract:
A piston ring is provided having a bottom surface, a top surface, an inner diameter surface and at least one running surface. A wear protection coating substantially entirely of cobalt is applied to the at least one running surface to protect the base material of the piston ring. Specifically, during operation of an engine, the more durable cobalt wear resistant coating, not the base material which may be steel or cast iron, is in sliding contact with a cylinder wall. The cobalt coating may be applied through, for example, electrodeposition or plasma spraying.
