ABSTRACT:
An article is coated with a multi-layer coating comprising at least one nickel layer deposited on the surface of the article, a palladium
ickel alloy layer deposited on the nickel layer, a refractory metal, preferably zirconium, layer deposited on the palladium
ickel alloy layer, a sandwich layer comprised of alternating layers of refractory metal compound and refractory metal deposited on the refractory metal layer, a refractory metal compound layer, preferably zirconium nitride, deposited on the sandwich layer, and a layer comprised of a refractory metal oxide or the reaction products of a refractory metal, oxygen and nitrogen deposited on the refractory metal compound layer. The coating provides the color of polished brass to the article and also provides abrasion and corrosion protection.
