Abstract

A plasma vapor deposited (PVD) coating method. The method includes overlaying a primer polymer layer onto a substrate surface. The method further includes overlaying a chrome metallic layer onto the primer polymer. The method also includes depositing a plasma vapor deposited (PVD) oxide layer of a thickness of 1 to 5 nanometers onto the chrome metallic layer and having a parameter of color change of the underlying chrome metallic layer. The color change may be determined according to the following equation:

Δ E* ab =√{square root over ((Δ L *) 2 +(Δ a *) 2 +(Δ b *) 2 )}

L is the color brightness of the oxide layer, and a and b are the color-component dimensions of the oxide and metallic layers. ΔE* ab may be less than 2.3. The method further includes overlaying an exposed polymeric layer onto the PVD oxide layer to form a protective layer at the interface between the exposed polymeric layer and the oxide layer.

First claim

What is claimed is:

1. A method comprising:
overlaying a primer polymer layer onto a substrate surface;
overlaying a chrome metallic layer onto the primer polymer;
depositing a plasma vapor deposited (PVD) oxide layer of a thickness of 1 to 5 nanometers onto the chrome metallic layer and having a parameter of color change of the underlying chrome metallic layer determined according to the following equation:
Δ E* ab =√{square root over ((Δ L *) 2 +(Δ a *) 2 +(Δ b *) 2 )}

wherein L is a color brightness of the oxide layer, and a and b are color-opponent dimensions of the PVD oxide and chrome metallic layers, wherein ΔE* ab is less than 2.3; and

overlaying an exposed polymeric layer onto the PVD oxide layer to form a protective layer at the interface between the exposed polymeric layer and the oxide layer.

2. The method of claim 1 , wherein the protective layer directly contacts the exposed polymeric layer and the oxide layer.

3. The method of claim 1 , wherein the protective layer includes urethane linkages formed between the exposed polymeric layer and the oxide layer.

4. The method of claim 1 , wherein the protective layer includes M-O—Si bonds formed between the exposed polymeric layer and the oxide layer.

5. The method of claim 4 , wherein the exposed polymeric layer includes a siloxane coupling agent.

6. The method of claim 1 , wherein the PVD oxide layer includes titanium oxide.

7. The method of claim 1 , wherein the exposed polymeric layer includes a carbamate clearcoat.

8. A method comprising:
overlaying a primer polymer layer onto a substrate surface;
overlaying a chrome metallic layer onto the primer polymer;
depositing a plasma vapor deposited (PVD) oxide layer of a thickness of 1 to 5 nanometers onto the chrome metallic layer and having a parameter of color change of the underlying chrome metallic layer determined according to the following equation:
Δ E* ab =√{square root over ((Δ L *) 2 +(Δ a *) 2 +(Δ b *) 2 )}

wherein L is a color brightness of the oxide layer, and a and b are color-opponent dimensions of the PVD oxide and chrome metallic layers, wherein ΔE* ab is less than 2.3; and

overlaying an exposed polymeric layer onto the PVD oxide layer to react the exposed polymeric layer and the oxide layer to form a protective layer at the interface.

9. The method of claim 8 , wherein the protective layer directly contacts the exposed polymeric layer and the oxide layer.

10. The method of claim 8 , wherein the protective layer includes urethane linkages formed between the exposed polymeric layer and the oxide layer.

11. The method of claim 8 , wherein the protective layer includes M-O—Si bonds formed between the exposed polymeric layer and the oxide layer.

12. The method of claim 11 , wherein the exposed polymeric layer includes a siloxane coupling agent.

13. The method of claim 8 , wherein the PVD oxide layer includes titanium oxide.

14. The method of claim 8 , wherein the exposed polymeric layer includes a carbamate clearcoat.

15. A method comprising:
plasma vapor depositing an oxide layer of a thickness of 1 to 5 nanometers onto a chrome metallic layer and having a color change parameter of the underlying metallic layer as follows:
Δ E* ab =√{square root over ((Δ L *) 2 +(Δ a *) 2 +(Δ b *) 2 )}

L is the oxide layer color brightness, a and b are color-opponent dimensions of the oxide and metallic layers, and ΔE* ab is less than 2.3; and

overlaying an exposed polymeric layer on the oxide layer to form a protective layer.

16. The method of claim 15 , further comprising overlying an exposed polymeric layer onto the oxide layer to react the exposed polymeric layer and the oxide layer to form a protective layer at the interface.

17. The method of claim 16 , wherein the protective layer directly contacts the exposed polymeric layer and the oxide layer.

18. The method of claim 16 , wherein the protective layer includes urethane linkages formed between the exposed polymeric layer and the oxide layer.

19. The method of claim 16 , wherein the protective layer includes M-O—Si bonds formed between the exposed polymeric layer and the oxide layer.

20. The method of claim 19 , wherein the exposed polymeric layer includes a siloxane coupling agent.
