Abstract
Official abstract text for this publication.
A coating system for a turbine engine component is disclosed. The coating system includes a substrate, an optional bond coat, a synthetic oxide layer and a top coat. The synthetic oxide layer is formed by atomic layer deposition and includes two or more oxides.
First claim
Opening claim text (preview).
What is claimed is: 1. A coating system comprising a substrate, a synthetic oxide layer disposed on the substrate and a top coat, wherein the synthetic oxide layer is formed by atomic layer deposition and comprises two or more oxides. 2. The coating system of claim 1 , wherein the substrate comprises a nickel based superalloy, an alloy of Al, Co, Fe, Mg, Ti, Zr, W, Mo or combinations thereof, or a Si-based material. 3. The coating system of claim 1 , wherein the two or more oxides comprises a primary oxide and a dopant. 4. The coating system of claim 3 , wherein the primary oxide comprises an oxide of Al, Cr, Si, Ti, Zr, Hf, Mg, Y, Ta, Nb, Yb, or combinations thereof. 5. The coating system of claim 3 , wherein the dopant comprises an oxide of La, Ce, Gd, Dy, Yb, Lu, Ca, Ba, Sr, or combinations thereof. 6. The coating system of claim 3 , wherein the synthetic oxide layer comprises a reaction product of the primary oxide and the dopant. 7. The coating system of claim 1 , wherein the synthetic oxide layer comprises a gradient of the two or more oxides. 8. The coating system of claim 1 , wherein the synthetic oxide layer comprises sublayers of differing oxide composition. 9. The coating system of claim 8 , wherein each sublayer has a thickness of 0.5 Angstroms to 10 micrometers. 10. The coating system of claim 8 , wherein the sublayers are arranged in a pattern. 11. The coating system of claim 1 , wherein the synthetic oxide layer comprises non-crystalline portions, crystalline portions, nanostructured portions, turbostratic portions, semi-crystalline portions or combinations of these. 12. The coating system of claim 1 , wherein the synthetic oxide layer has a thickness of 100 nanometers to 10 micrometers. 13. The coating system of claim 1 , wherein the top coat comprises a thermal barrier coating, an environmental barrier coating, abradable coating, erosion resistant coating, or a coating that provides a combination of such functions. 14. The coating system of claim 1 , wherein the synthetic oxide layer comprises an oxide which is the reaction product of the two oxides. 15. The coating system of claim 1 , wherein the synthetic oxide layer further comprises a nitride.
