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.
Claims26
A device comprising:
- a substrate;
- a first coating deposited over the substrate, wherein the first coating comprises at least one of a metal, a metal compound, a material comprising a metallic property, a metallic compound, a metal alloy, or a compound comprising a metallic property;
- and
- a second coating deposited over the first coating, wherein the first coating is interposed between the substrate and the second coating, wherein the second coating is outermost, wherein the substrate, the first coating, and the second coating define at least one of a jewelry item or a component of a jewelry item, wherein the second coating comprises at least one member from at least one of a first group or a second group,
- wherein the first group comprises at least one of chromium-titanium nitride (CrTiN), aluminum-titanium nitride (AlTiN), aluminum-titanium-chromium nitride (AlTiCrN), tungsten nitride (WN), tungsten carbide, tungsten, zirconium, cobalt chrome, cobalt chromium, nitinol, aluminum carbide, vanadium, copper, brass, bronze, tungsten copper, zinc, tin, German silver, niobium, molybdenum, hafnium, chromium, a steel alloy, silver nitride, aluminum nitride, vanadium nitride, tantalum nitride, chromium carbide, tantalum carbide, or cobalt chrome molybdenum, but excludes titanium carbide, titanium nitride, titanium boride, hafnium carbide, hafnium nitride, hafnium boride, zirconium carbide, zirconium nitride, and zirconium boride,
- wherein the second group comprises at least one of cobalt, tantalum, iron or nickel, and wherein the second group excludes titanium carbide, titanium nitride, titanium boride, hafnium carbide, hafnium nitride, hafnium boride, zirconium carbide, zirconium nitride, zirconium boride, gold and platinum.
