ABSTRACT:
A multi-layer plating and method are provided for improved corrosion resistance of ferrous metal substrates and articles made therefrom. The multi-layer plating comprises a metallic coating comprising a layer of zinc or cadmium and a layer of tin, each of which are preferably between 0.00001 to 0.001 inches in thickness, followed by a layer, preferably between about 0.0001 to 0.000001 inches in thickness of either chromium or a metallic chromium substitute. The method comprises plating, and preferably electroplating, the aforementioned layers of metal over an article having ferrous metal base stock to obtain improved corrosion resistance.
