ABSTRACT:
In a mechanical plating process, lubricant particles can be coated on a metal substrate together with the particulate plating metal to enhance the mechanically-applied coating's lubricity. The lubricant can be particles of fluorocarbon polymers, fluorocarbon-hydrocarbon blended polymers, powdered, elemental carbon, powdered fluorinated carbon, or mixtures thereof. The lubricant particles have a diameter less than the thickness of the coating (which is usually from 2.5 to 132.5 mils), so they will not be dislodged from the coating. The particles must not be too small or they may be washed away by plating liquids or may be applied too far from the coating surface to enhance lubricity. These dimensional relationships insure that the lubricant particles are entrapped within the coating.
