Abstract

An article is coated with a multilayer coating comprising a nickel layer deposited on the surface of the article, a palladium layer deposited on the nickel layer, a ruthenium layer deposited on the palladium layer, a refractory metal, preferably zirconium, layer deposited on the ruthenium layer, and a refractory metal compound, preferably zirconium nitride, deposited on the refractory metal layer. The coating provides the color of polished brass to the article and also provides abrasion and corrosion protection.
