Abstract
A method of treating the surface of a metal sliding contact which involves the immersion of the metal contact in an acid bath, in the presence of an electrolytic current to produce pockets bounded by crystalline projections. A lubricant is applied to the contact to fill the pockets therein and the crystalline projections are bent over to trap the lubricant.
Claims10
A method of forming a metal contact surface for sliding engagement with another surface, said method comprising:
- (a) treating said metal surface to form a plurality of metallic crystalline projections thereon with the areas between said projections penetrating the substrate of said metal surface and constituting reservoir means therein for containing a solid lubricant;
- (b) applying a solid lubricant to the resulting treated surface to fill said reservoir means;
- and
- (c) causing said crystalline projections to be bent over said reservoirs to entrap said sold lubricant within the reservoirs by applying gradually increasing pressure on said metal surface so that said crystalline projections are bent relative to the remainder of said metal surface.
