Title: Coated components and methods of fabricating coated components and coated turbine disks.
Abstract: Coated components and methods of fabricating coated components and coated turbine disks are provided. In an embodiment, by way of example only, a coated component includes a substrate comprising a superalloy in an unmodified form and a coating disposed over the substrate, where the coating comprises the superalloy in a modified form. The modified form of the superalloy includes, by weight, at least 10% more chromium and at least 10% more of one or more noble metals than the unmodified form of the superalloy, and the modified form of the superalloy is substantially free of aluminum ...

CROSS-REFERENCES TO RELATED APPLICATIONS

This application is a divisional of U.S. patent application Ser. No. 12/273,843, filed Nov. 19, 2008.

TECHNICAL FIELD

The inventive subject matter generally relates to turbine engine components, and more particularly relates to coatings for turbine disks and methods of fabricating coated turbine disks.

BACKGROUND

Turbine engines are used as the primary power source for various kinds of aircraft. The engines may also serve as auxiliary power sources that drive air compressors, hydraulic pumps, and industrial electrical power generators. Most turbine engines generally follow the same basic power generation procedure. Compressed air is mixed with fuel and burned, and the expanding hot combustion gases are directed against stationary turbine vanes in the engine. The vanes turn the high velocity gas flow partially sideways to impinge onto turbine blades mounted on a rotatable turbine disk. The force of the impinging gas causes the turbine disk to spin at high speed. Jet propulsion engines use the power created by the rotating turbine disk to draw more air into the engine, and the high velocity combustion gas is passed out of the gas turbine aft end to create forward thrust.

Turbine engines typically operate more efficiently with increasingly hotter operating temperatures. Accordingly, to maximize the engine efficiency, attempts have been made to form turbine engine components having higher operating temperature capabilities. For example, turbine disks are typically made of nickel-based superalloys or cobalt-based superalloys, which exhibit strength and creep resistance at relatively high temperatures (e.g., 704° C. or 1300° F.), as well as resistance to fatigue crack initiation. However, as turbine disks are increasingly being exposed to operating temperatures above 704° C. (1300° F.), the aforementioned superalloys from which they are fabricated may not be adequately corrosion-resistant in such environments. In particular, the superalloys may be susceptible to salt attacks, which may decrease the useful life of the turbine disk.

Hence, there is a need for materials and components that may be more corrosion-resistant when exposed to engine operating temperatures that exceed 704° C. (1300° F.). In addition it is desirable for materials to be relatively inexpensive to implement into turbine engine component manufacturing processes. Moreover, it is desirable for the manufacturing process to be relatively simple to perform.

BRIEF

SUMMARY

Coated components and methods of fabricating coated components and coated turbine disks are provided.

In an embodiment, by way of example only, a coated component includes a substrate comprising a superalloy in an unmodified form and a coating disposed over the substrate, where the coating comprises the superalloy in a modified form. The modified form of the superalloy includes, by weight, at least 10% more chromium and at least 10% more of one or more noble metals than the unmodified form of the superalloy, and the modified form of the superalloy is substantially free of aluminum.

In another embodiment, by way of example only, a method of fabricating a coated component includes chromizing a substrate comprising a superalloy to form a chromium-enriched exterior portion of the substrate and diffusing a noble metal into the chromium-enriched exterior portion of the substrate to form the coated component.

In still another embodiment, by way of example only, a method of fabricating a coated turbine disk includes chromizing a substrate comprising a superalloy to form a chromium-enriched exterior portion of the substrate, cleaning a surface of the chromium-enriched exterior portion of the substrate, electroplating a noble metal to the surface of the chromium-enriched exterior portion of the substrate to form an electroplated substrate, and heat treating the electroplated substrate to diffuse the noble metal therein to form the coated turbine disk.

BRIEF DESCRIPTION OF THE DRAWINGS

The inventive subject matter will hereinafter be described in conjunction with the following drawing figures, wherein like numerals denote like elements, and

FIG. 1 is a perspective view of a coated turbine engine component, according to an embodiment;

FIG. 2 is a sectional view of a portion of the coated turbine engine component of FIG. 1, according to an embodiment; and

FIG. 3 is a flow diagram of a method of fabricating a coated component, according to an embodiment.

DETAILED DESCRIPTION

The following detailed description is merely exemplary in nature and is not intended to limit the inventive subject matter or the application and uses of the inventive subject matter. In particular, although the inventive subject matter is described as being applied to a turbine disk, it will be appreciated that the inventive subject matter may be incorporated onto any other components that may be exposed to temperatures and gases that may exceed 704° C. (1300° F.). Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
