Abstract
In a metal material having a surface adapted to slide on a surface having a nickel-silicon carbide composite electroplated layer and subjected to a treatment for causing silicon carbide particles to project outward beyond the surface, the surface of the metal material is provided with porous hard chrome plating, whereby a lubricant may be deposited and retained in the porous plated layer.
Claims4
In combination, a first member containing a surface of porous hard chromium, and a second member containing a composite electroplated surface wherein silicon carbide particles project outwardly beyond a nickel matrix, said surface of porous hard chromium and said composite electroplated surface being in sliding engagement, whereby lubricant may be retained both by said porous hard chromium and on said composite electroplated surface between said projecting silicon carbide particles.
