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.
Claims12
An article 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
- an external metallic coating such that the external metallic coating is outermost, wherein the external metallic 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, tantalum carbide, or cobalt chrome molybdenum, or any combination thereof, but excludes titanium carbide, titanium nitride, titanium boride, hafnium carbide, hafnium nitride, hafnium boride, zirconium carbide, zirconium nitride, zirconium boride, and stainless steel,
- wherein the second group comprises at least one of cobalt, tantalum, iron, or nickel, 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.

A method for making an article comprising a substrate, a first coating comprising 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 an external metallic coating, the method comprising:
- forming the substrate into a desired shape;
- depositing the first coating onto the substrate;
- and
- depositing the external metallic coating onto the first coating such that the external metallic coating is outermost, wherein the external metallic 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, cobalt chrome, cobalt chromium, nitinol, aluminum carbide, vanadium, copper, brass, bronze, tungsten copper, zinc, tin, German silver, niobium, molybdenum, hafnium, rhenium, tantalum, chromium, a steel alloy, silver nitride, aluminum nitride, vanadium nitride, tantalum nitride, chromium carbide, tantalum carbide, cobalt chrome molybdenum, or any combination thereof, but excludes titanium carbide, titanium nitride, titanium boride, hafnium carbide, hafnium nitride, hafnium boride, zirconium carbide, zirconium nitride, zirconium boride, and stainless steel,
- wherein the second group comprises at least one of cobalt, tantalum, iron, or nickel, 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.
