Abstract (en)
[origin: US4745035A] The article is provided with a coating resisting wear and corrosion, such coating being for the most part made of a precious metal or alloy of a precious metal, for example gold or an alloy containing gold. The coating is made up of a first layer of such precious metal or alloy thereof comprising discrete inclusions of a metallic compound such as titanium nitride. These inclusions are deposited along with the precious metal in vapor phase and distributed in a substantially homogeneous manner through the entire thickness of the layer, said thickness being equal to or greater than 0.4 mu m. A second layer of precious metal or alloy thereof is located between the article and said first layer. The article may be a watch case, a bracelet link or a piece of jewelry.
