Abstract
The present invention relates generally to a coated jewelry article or a coated component of a jewelry article, comprising a jewelry article or a component of a jewelry article, a first metallic coating, and a second metallic coating.
Claims25
A two layer coated jewelry item or a two layer coated component of a jewelry item, consisting of:
- a substrate;
- a first coating comprising a metal, a metal compound, a material having metallic properties, a metallic compound, a metal alloy, or a compound having metallic properties, wherein the first coating is coupled to the substrate;
- and
- a second coating deposited over the first coating and selected from at least one of the items from at least one of the following groups:
- (a) zirconium nitride (ZrN), chromium-titanium nitride (CrTiN), aluminum-titanium nitride (AITiN), aluminum-titanium-chromium nitride (AITiCrN), tungsten nitride (WN), tungsten carbide, tungsten, zirconium, cobalt chrome, cobalt chromium, nitinol, aluminum, aluminum carbide, vanadium, copper, brass, bronze, tungsten copper, zinc, tin, German silver, niobium, molybdenum, hafnium, rhenium, chromium, a steel alloy, silver nitride, aluminum nitride, vanadium nitride, tantalum nitride, chromium carbide, zirconium carbide, tantalum carbide, and cobalt chrome molybdenum, or
- (b) cobalt, tantalum, iron and nickel, but excluding gold.
