ABSTRACT:
The present invention provides a method of improving the corrosion resistance of a ferrous metal substrate by providing a non-ferrous corrosion resistant plated undercoating by steps of sequentially plating onto the substrate a first layer of copper of about 0.00015 to 0.0005 inches in thickness, a layer of zinc of about 0.0002 to 0.0005 inches in thickness and a second layer of copper of about 0.00015 to 0.0005 inches in thickness and, optionally, multiples of such zinc and copper layers, and thereafter subjecting the plated substrate to a thermal treatment sufficient to effect partial diffusion at the respective interfaces of each of the layers of copper and zinc to provide zones of non-homogeneous copper-zinc alloy of infinitely variable linear distribution of copper and zinc.
