摘要： 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.

摘要： 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.

摘要： 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.
