Abstract
A method for plating a graphite aluminum metal matrix composite material with nickel and gold utilizes the steps of: cleaning a surface of the metal matrix composite material so as to substantially remove grease and particulates therefrom; forming a layer of copper upon the surface of the metal matrix composite material; heating the copper layer to drive out entrapped fluids; applying acid to the copper layer to remove oxidation therefrom; forming a layer of nickel upon at least a portion of the layer of copper; heating the nickel layer to relieve stress therein; and electrolytically forming a layer of gold upon at least a portion of the layer of nickel.
