摘要： A cast turbine airfoil to which a squealer tip is added. The turbine airfoil is cast slightly undersize. The squealer tip is comprised of an alloy that is different from the cast alloy of the airfoil, the oxidation resistance and strength of the squealer tip alloy being greater than the strength of the turbine airfoil alloy. The cast turbine alloy having the added squealer tip can utilize a material in the squealer tip that is more difficult to cast than the cast alloy material, yet is more suited for severe environmental conditions and temperature extremes.

摘要： A nickel-base superalloy article has a surface protective layer comprising nickel, from about 20 to about 35 weight percent aluminum, and from about 0.5 to about 10 weight percent rhenium. The protective layer, which is preferably an overlay coating of the beta (&bgr;) phase NiAl form, is formed by depositing nickel, aluminum, rhenium, and modifying elements onto the substrate surface. A ceramic layer may be deposited overlying the protective layer.

摘要： A diffusion aluminide coating having a graded structure is applied over a nickel base superalloy substrate. The coating has an inner region of a diffusion aluminide adjacent to the substrate rich in a reactive element, typically Hf, Si or combinations of the two. The near surface region is a diffusion aluminide which is substantially free of reactive elements. Such coatings when used as bond coats in thermal barrier coating systems exhibit improved spallation performance.

摘要： According to an embodiment of the invention, a method for repairing a coated high pressure turbine blade, which has been exposed to engine operation, to restore coated airfoil contour dimensions of the blade, is disclosed. The method comprises providing an engine run high pressure turbine blade including a base metal substrate made of a nickel-based alloy and having thereon a thermal barrier coating system. The thermal barrier coating system comprises a diffusion bond coat on the base metal substrate and a top ceramic thermal barrier coating comprising a yttria stabilized zirconia material. The top ceramic thermal barrier coating has a nominal thickness t. The method further comprises removing the thermal barrier coating system, wherein a portion of the base metal substrate also is removed, and determining the thickness of the base metal substrate removed. The portion of the base metal substrate removed has a thickness, Δt. The method also comprises reapplying the diffusion bond coat to the substrate, wherein the bond coat is reapplied to a thickness, which is about the same as applied prior to the engine operation; and reapplying the top ceramic thermal barrier coating to a nominal thickness of t+Δt, wherein Δt compensates for the portion of removed base metal substrate. Advantageously, the coated airfoil contour dimensions of the high pressure turbine blade are restored to about the coated dimensions preceding the engine run.

摘要： A metallic substrate has a substrate surface having a substrate surface of nickel, a substrate aluminum content, and other alloying elements. A maskant is applied overlying the substrate surface to produce a masked substrate surface having an exposed region and a protected region. The maskant includes a plurality of maskant particles, each particle having a maskant particle composition comprising a maskant metal selected from the group of nickel, cobalt, titanium, chromium, iron, and combinations thereof, and a maskant aluminum content. The substrate is aluminided by contacting a source of aluminum to the masked substrate surface, whereby aluminum deposits on the exposed region and does not deposit on the protected region.

摘要： A method for producing a thermal barrier coating system on an article that will be subjected to a hostile environment. The thermal barrier coating system is composed of a metallic bond coat and a ceramic thermal barrier coating having a columnar grain structure. The method generally entails forming the bond coat on the surface of a component, and then grit blasting the bond coat with an abrasive media having a particle size of greater than 80 mesh. The component is then supported within a coating chamber containing at least two ingots of the desired ceramic material. An absolute pressure of greater than 0.014 mbar is established within the chamber containing oxygen and an inert gas. Thereafter, the ceramic ingots are vaporized with an electron beam such that the vapor deposits on the surface of the component to form a layer of the ceramic material on the surface.

摘要： A method of depositing a ceramic thermal barrier coating on an article that will be subjected to a hostile environment, such as turbine, combustor and augmentor components of a gas turbine engine. The thermal barrier coating is deposited by electron beam physical vapor deposition (EBPVD) using process parameters that include an absolute pressure of greater than 0.010 mbar and an oxygen partial pressure of greater than 50%, preferably at or close to 100%. Under these conditions, the desired ceramic material is evaporated with an electron beam to produce a vapor that deposits on the component to form a thermal barrier coating of the ceramic material.
