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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
97 words
A method of plating an aluminum substrate comprising: coating said aluminum substrate with an intermediate metallic coating comprising between about 0.01% and about 99.99% nickel and between about 99.99% and about 0.01% tin and having a thickness between about 0.005 mil and about 3 mils; plating a metal selected from the group consisting of copper and nickel onto the intermediate metallic coating; and heating the coated and plated aluminum substrate to form an alloy between said aluminum substrate and said intermediate metallic coating and to form an alloy between said intermediate metallic coating and the plated metal.
Claim 2
Independent Claim
97 words
A method of plating an aluminum substrate comprising: coating said aluminum substrate with an intermediate metallic coating comprising between about 0.01% and about 99.99% nickel and between about 99.99% and about 0.01% tin and having a thickness between about 0.005 mil and about 3 mils; plating a metal selected from the group consisting of copper and nickel onto the intermediate metallic coating; and heating the coated and plated aluminum substrate to form an alloy between said aluminum substrate and said intermediate metallic coating and to form an alloy between said intermediate metallic coating and the plated metal.
