Abstract

A composite article includes a substrate and a powder-derived composite coating on the substrate. The composite coating includes discrete regions of a first material and discrete regions of a second material. At least one of the first material or the second material is a chemical precursor.

First claim

What is claimed is:

1. A composite article comprising:
a substrate; and
a fully powder-derived composite coating disposed on the substrate and including discrete, elongated regions of a first material and discrete, elongated regions of a second material, and at least one of the first material or the second material is a chemical precursor, wherein the first material is the chemical precursor and is selected from a group consisting of sol-gel precursor material, oligomeric material and combinations thereof, and the second material is a metal selected from a group consisting of cobalt, copper and combinations thereof.

2. The composite article as recited in claim 1 , wherein the chemical precursor is a material selected from a group consisting of nickel acetylacetonate, nickel octanoate, nickel oxalate, nickel stearate, silicon alkoxide, and combinations thereof.

3. The composite article as recited in claim 1 , wherein the first material is the chemical precursor and is present in an amount that is greater than an amount of the second material.

4. The composite article as recited in claim 1 , further comprising a bond layer between the substrate and the powder-derived composite coating.

5. The composite article as recited in claim 4 , wherein the bond layer is selected from a group consisting of a metallic material, intermetallic material, glass material, ceramic material, and combinations thereof.

6. The composite article as recited in claim 4 , wherein the bond layer is selected from a group consisting of silicon metal, refractory metal, and combinations thereof.

7. The composite article as recited in claim 1 , further comprising a topcoat on the powder-derived composite coating.

8. The composite article as recited in claim 1 , wherein the substrate is a ceramic material.

9. The composite article as recited in claim 8 , wherein the ceramic material is a ceramic matrix composite comprising a silicon carbide matrix.

10. The composite article as recited in claim 1 , wherein the substrate is selected from a group consisting of glass and glass matrix composites.

11. The composite article as recited in claim 1 , wherein the first material is the oligomeric material.

12. The composite article as recited in claim 1 , wherein the first material is the sol-gel precursor material.

13. The composite article as recited in claim 1 , wherein the second material is the cobalt.

14. The composite article as recited in claim 1 , wherein the second material is the copper.

15. A composite article comprising:
a substrate; and
a fully powder-derived composite coating disposed on the substrate and including discrete, elongated regions of a first material and discrete, elongated regions of a second material, and at least one of the first material or the second material is a chemical precursor, wherein the chemical precursor is a material selected from the group consisting of nickel acetylacetonate, nickel octanoate, nickel oxalate, nickel stearate, silicon alkoxide, and combinations thereof.

16. The composite article as recited in claim 15 , wherein the material is selected from the group consisting of nickel acetylacetonate, nickel octanoate, nickel oxalate, nickel stearate and combinations thereof.

17. The composite article as recited in claim 15 , wherein the material is the silicon alkoxide.
