Abstract

An article is coated with a multi-layer coating having a bronze color. The coating comprises a polymeric basecoat layer, and a color and protective stack layer comprised of layers of carbon-rich refractory metal or refractory metal alloy carbonitride alternating with layers of nitrogen-rich refractory metal or refractory metal alloy carbonitride.

Claims

1. An article having on at least a portion of its surface a multi-layer coating having a bronze color comprising:

polymeric basecoat layer;

color and parotective stack layer comprised of layers of carbon-rich refractory metal carbonitride or carbon-rich refractory metal alloy carbonitride alternating with layers of nitrogen-rich refractory metal carbonitride or nitrogen-rich refractory metal alloy carbonitride,

wherein the carbon-rich carbonitride contains, a carbon content between 25 to 50 atomic percent and a nitrogen content between 5 to 35 atomic percent, wherein said carbon-rich refractory metal carbonitride or carbon-rich refractor metal alloy carbonitride contains a small amount of oxygen ranging from 2 to 15 atomic percent, and

wherein the nitrogen-rich carbonitride contains a nitrogen content between 25 to 50 atomic percent and carbon content between 5 to 35 atomic percent.

2. The article of claim 1 wherein a strike layer comprised of refractory metal or refractory metal alloy is intermediate said basecoat layer and said color stack layer.

3. The article of claim 1 wherein a strengthening layer is over said basecoat layer.

4. The article of claim 3 wherein said strengthening layer is comprised of chromium.

5. The article of claim 2 wherein a strengthening layer is intermediate said basecoat layer and said strike layer.

6. The article of claim 5 wherein said strengthening layer is comprised of chromium.

7. The article of claim 5 wherein an oxide layer comprised of refractory metal oxide or refractory metal alloy oxide is on said color stack layer.

8. The article of claim 5 wherein an oxy-nitride layer comprised of reaction products of refractory metal or refractory metal alloy, oxygen and nitrogen is on said color stack layer.

9. The article of claim 2 wherein an oxide layer comprised of refractory metal oxide or refractory metal alloy oxide is on said color stack layer.

10. The article of claim 2 wherein an oxy-nitride layer comprised of reaction products of refractory metal or refractory metal alloy, oxygen and nitrogen is on said color stack layer.

11. The article of claim 1 wherein an oxy-nitride layer comprised of reaction products of refractory metal or refractory metal alloy, oxygen and nitrogen is on said color stack layer.

12. The article of claim 1 wherein said nitrogen-rich refractory metal carbonitride or nitrogen-rich refractory metal alloy carbonitride contains a small amount of oxygen ranging from 2 to 15 atomic percent.

13. An article having on at least a portion of its surface a multi-layer coating having a bronze color comprising:

polymeric basecoat;

strengthening layer;

strike layer comprised of refractory metal or refractory metal alloy;

color and protective stack layer comprised of layers of carbon-rich refractory metal carbonitride or carbon-rich refractory metal alloy carbonitride alternating with layers of nitrogen-rich refractory metal carbonitride or nitrogen-rich refractory metal alloy carbonitride,

wherein the carbon-rich carbonitride contains, a carbon content between 25 to 50 atomic percent and a nitrogen content between 5 to 35 atomic percent, wherein said carbon-rich refractory metal carbonitride or carbon-rich refractory metal alloy carbonitride contains a small amount of oxygen ranging from 2 to 15 atomic percent, and

wherein the nitrogen-rich carbonitride contains a nitrogen content between 25 to 50 atomic percent and carbon content between 5 to 35 atomic percent.
