Date Jan. 25, 1996In a method for removing metal from the surface of a workpiece by continuously rubbing the surface with a tool in a friction-inducing manner and in the presence of a friction-enhancing agent (an anti-lubricant) and in which a thin layer of the friction-enhancer must be available at the tool surface, there is provided a tool which carries the friction-enhancing agent in the form of a composition of an abrasive and a rubbery solid siloxane reaction product admixed with a liquid, mobile, anti-lubricant siloxane stably dispersed therewithin, and the use of the tool to excoriate and condition the surface by removing therefrom the oxide film thereon and leaving its place a siloxane film, and a conditioned metal surface having siloxane molecules each individually bonded directly to the metal over a relatively large area of the surface to provide a relatively uniform siloxane layer.</p> |
