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