Abstract
Abstract A method of plating a metallic substrate by coating said substrate with a specific metallic system; plating at least one metal onto the coating; and heating the coated and plated metallic substrate to a temperature that effects a bonding of said metallic substrate to said coating and the plated metal. The method is utilized to plate metals onto metal substrates; including substrates such as aluminum and zinc.
