Abstract

A composition includes aluminum (Al), and a blend of a carbide and nickel-chromium (Ni-20Cr). The method of applying a coating composition includes blending a carbide and nickel-chromium (Ni-20Cr) with aluminum (Al) to form a composition, the carbide and the nickel-chromium (Ni-20Cr) in a range between 90% and about 99.5% by weight of the composition, and wherein the aluminum (Al) is in a range between about 0.5% and less than about 10% by weight of the composition; and spraying the composition on the turbine component.

Claims (28)

1 . A composition comprising: a blend of a carbide and nickel chromium, wherein the overall weight of the blend of the carbide and the nickel-chromium is in a range between 90% and about 99.5% by weight of the composition; and

aluminum,

wherein the carbide includes at least one of molybdenum carbide, titanium carbide, silicon carbide, aluminum carbide, and combinations thereof.

2 . A composition according to claim 1 , wherein the blend of the carbide and the nickel-chromium includes by weight, 25% nickel-chromium.

3 . A composition according to claim 1 , wherein the aluminum is in a range between about 0.5% and less than about 10% by weight of the composition.

4 . A composition according to claim 1 , wherein the aluminum is in range between about 5% and about 10% by weight of the composition.

5 . A composition according to claim 1 , wherein the aluminum is in a range between about 6% and about 10% by weight of the composition.

6 . A composition according to claim 1 , wherein the aluminum is in a range between about 7% and about 1011% by weight of the composition.

7 . A composition according to claim 1 , wherein the aluminum is in a range between about 8% and about 1011% by weight of the composition.

8 . A composition according to claim 1 , wherein the aluminum is in a range between about 8.5% and about 9.5% by weight of the composition.

9 . A composition according to claim 1 , wherein the aluminum is about 9% by weight of the composition.

10 . A coated turbomachine component, comprising:

a turbomachine component; and

a coating including:

a blend of a carbide and nickel-chromium; and aluminum, in a range between about 5% and about 11% by weight of the composition,

wherein the carbide includes at least one of molybdenum carbide, titanium carbide, silicon carbide, aluminum carbide, and combinations thereof.

11 . A coated turbomachine component according to claim 10 , wherein the blend of the carbide and the nickel-chromium includes, by weight, 25% nickel-chromium.

12 . A coated turbomachine component according to claim 10 , wherein the overall weight of the blend of the carbide and the nickel-chromium is in a range between 90% and about 99.5% by weight of the composition.

13 . A coated turbomachine component according to claim 10 , wherein the aluminum (Al) is about 9% by weight of the composition.

14 . A coated turbomachine component according to claim 10 , wherein the aluminum is in a range between about 6% and about 11% by weight of the composition.

15 . A coated turbomachine component according to claim 10 , wherein the aluminum is in a range between about 7% and about 11% by weight of the composition.

16 . A coated turbomachine component according to claim 10 , wherein the aluminum is in a range between about 8% and about 11% by weight of the composition.

17 . A coated turbomachine component according to claim 10 , wherein the aluminum is in a range between about 8.5% and about 9.5% by weight of the composition.

18 . A coated turbomachine component according to claim 10 , wherein the aluminum is about 9% by weight of the composition.

19 . A method of applying a coating to a turbomachine component, the method comprising:

blending a carbide and nickel-chromium with aluminum to form a composition, the carbide and the nickel-chromium in a range between 90% and about 99.5% by weight of the composition, and wherein the aluminum is in a range between about 0.5% and less than about 10% by weight of the composition; and

spraying the composition on the turbomachine component,

wherein the carbide includes at least one of molybdenum carbide, titanium carbide, silicon carbide, aluminum carbide, and combinations thereof.
