Abstract: Methods of processing compositions containing titanium and aluminum, especially titanium aluminide intermetallic compositions (TiAl intermetallics) based on the TiAl (gamma) intermetallic compound. The methods entail processing steps that include a hot isostatic pressing (HIP) cycle and a heat treatment cycle that can be performed in a single vessel. TiAl intermetallic compositions processed in this manner preferably exhibit a duplex microstructure containing equiaxed and lamellar morphologies.

Abstract: An environmental coating suitable for use on turbine components, such as turbine disks and turbine seal elements, formed of alloys susceptible to oxidation and hot corrosion. The environmental coating is predominantly a solid solution phase of nickel, iron, and/or cobalt. The coating contains about 18 weight percent to about 60 weight percent chromium, which ensures the formation of a protective chromia (Cr2O3) scale while also exhibiting high ductility. The coating may further contain up to about 8 weight percent aluminum, as well as other optional additives. The environmental coating is preferably sufficiently thin and ductile to enable compressive stresses to be induced in the underlying substrate through shot peening without cracking the coating.

Abstract: A method for restoring thickness to load-bearing components of gas turbine engines, and for repairing a honeycomb structured gas turbine engine component. A surface of the component such as the backing surface of a honeycomb component after honeycomb removal is roughened and cleaned. A selected build-up material is deposited onto the substrate by high velocity oxy-fuel deposition or low pressure plasma spray. The component is heat treated to enhance the bond between the deposited material particles, and between the deposited material and the substrate by diffusion.

Abstract: A gas turbine component, such as a turbine disk or a rotating seal, is fabricated by furnishing a substrate shaped as a gas turbine component made of a nickel-base superalloy, and oxidizing the substrate to produce an oxidized substrate having thereon a layer comprising an oxide and having a thickness of at least about 500 Angstroms. The step of oxidizing is performed prior to entry of the component into service and in an atmosphere that does not contain combustion gas. The oxidized gas turbine component is thereafter placed into service.

Abstract: An internal passage of an article such as a gas turbine airfoil is coated with an aluminum-containing coating. To accomplish this coating process, a coating slurry of a mixture of a carrier component of water and a hectorite clay or a bentonite clay, together with a solids component of a source of aluminum, a halide activator, and an oxide dispersant, is prepared. The coating slurry is applied to the internal passage of the gas turbine airfoil and dried. The gas turbine airfoil and the applied coating slurry are heated to form an aluminum-containing coating bonded to the internal passage of the gas turbine airfoil. Excess coating material is removed from the article internal passage.
