ABSTRACT:
A method of treating metal sliding contact surfaces is disclosed. The method comprises pitting the surface (as by shot-blasting with glass or sand), impregnating the pitted surface with a dry lubricant (such as powdered graphite or MoS.sub.2), and roughening the impregnated surface to partially close the pits and to generate "peaks" of metal which are worn away during a bedding-in of the interengaging sliding contact surfaces.
