Abstract

Coated articles are disclosed. One embodiment of a coated article includes a substrate capable of being subjected to corrosion and a deposited coating on the substrate. The deposited coating has silicon with the substrate resisting corrosion with the deposited coating on the substrate when exposed to 15% NaClO by a rate of at least 5% greater than the corrosion rate of a coating applied with the same process but without introducing the deposition gas at the sub-decomposition temperature and/or the substrate with the deposited coating having a 15% NaClO corrosion rate of between 0 and 3 mils per year.

First claim

What is claimed is:

1. A coated article, comprising:
a substrate capable of being subjected to corrosion; and
a deposited coating on the substrate, the deposited coating having silicon;
wherein one or both of:
the substrate resists the corrosion with the deposited coating on the substrate when exposed to 15% NaClO; and
the substrate with the deposited coating has a 15% NaClO corrosion rate of between 0 and 3 mils per year.

2. The coated article of claim 1 , wherein the substrate is stainless steel.

3. The coated article of claim 1 , wherein the substrate is a nickel-based alloy.

4. The coated article of claim 1 , wherein the substrate is ferrous.

5. The coated article of claim 1 , wherein the substrate is non-ferrous.

6. The coated article of claim 1 , wherein the substrate is tempered.

7. The coated article of claim 1 , wherein the substrate is non-tempered.

8. The coated article of claim 1 , wherein the substrate has an equiaxed microstructure.

9. The coated article of claim 1 , wherein the substrate has a directionally-solidified microstructure.

10. The coated article of claim 1 , wherein the substrate has a crystal microstructure.

11. The coated article of claim 1 , wherein the substrate is ceramic surface.

12. The coated article of claim 1 , wherein the substrate is a glass surface.

13. The coated article of claim 1 , wherein the substrate is ceramic matrix composite surface.

14. The coated article of claim 1 , wherein the substrate is a composite metal surface.

15. The coated article of claim 1 , wherein the coated article has a polarization-field loop that is linear.
