PURPOSE: A method for reducing the galvanic corrosion of dissimilar metals in contact with one another wherein the exposed surface of the more noble metal is coated with a metal more galvanically compatible with the less noble metal. CONSTITUTION: In accordance with the present invention, in an article made of two metals, one being more noble than the other, the outer surface of the more noble metal is treated with a metal which is galvanically compatible with the less noble metal to form a protective layer between the two dissimilar metals which prevents the reduction reaction of the galvanic couple from occurring. The invention greatly reduces the oxidation reduction process which occurs when two dissimilar metals are in contact with one another in the presence of an electrolyte.
