Abstract
Adherent metal coatings of metals that cannot be adherently applied directly onto a desired substrate metal by chemical vapor deposition at a temperature below about 300.degree. C. are obtained by applying an adherent metal undercoating to the surface of the metal substrate which weakly or not at all chemisorbs carbon monoxide, then applying the desired outercoat metal to the undercoat substrate by chemical vapor deposition, using a heat decomposable metal carbonyl as the source of the desired outer coating metal. The undercoating metal may be applied by conventional plating processes such as electroplating or electroless plating. In preferred embodiments, the substrate is iron or steel or their alloys, the undercoating metal is copper, and the outer coating metal is a ferrous metal, i.e., nickel, iron, or cobalt.
