Abstract
A method is disclosed for rendering steel articles corrosion resistant, wherein on the steel article surface two layers are deposited, one whereof comprises nickel and the other copper, the coated article being successively subjected to an annealing step at high temperature under a reducing gas atmosphere. interdiffusion of the Cu and Ni gives rise to a single coating layer with a compositional variation across its thickness. The layers may be initially applied by any known method e.g. electrochemical, chemical, flame spraying, plasma, etc. The annealing step may take place in an atmosphere containing hydrogen at a temperature of 950-1150 DEG C.
