  • Patent number: 6168871
    Abstract: A method for forming an exterior surface of a high-temperature component, such as a blade or vane of a gas turbine engine. The method entails forming a shell by a powder metallurgy technique that yields an airfoil whose composition can be readily tailored for the particular service conditions of the component. The method generally entails providing a pair of inner and outer mold members that form a cavity therebetween. One or more powders and any desired reinforcement material are then placed in the cavity and then consolidated at an elevated temperature and pressure in a non-oxidizing atmosphere. Thereafter, at least the outer mold member is removed to expose the consolidated powder structure. By appropriately shaping the mold members to tailor the shape of the cavity, the consolidated powder structure has the desired shape for the exterior shell of a component, such that subsequent processing of the component does not require substantially altering the configuration of the exterior shell.

  • Patent number: 6164916
    Abstract: A method of applying a wear-resistant hardface material (alloy) to a portion of a turbine blade, typically a wear surface on a shrouded turbine blade. A thin foil of brazing alloy (which in the preferred embodiment is a nickel-based alloy) is placed over said wear surface, and a hardface alloy of a greater than desired thickness (which in the preferred embodiment is a cobalt-based alloy) is placed thereover, thereby sandwiching the foil therebetween. The wear surface, foil, and hardface material are heated for a period sufficient to melt the foil and cause bonding of the hardface alloy to the wear surface. The hardface material is thereafter machined to bring the wear surface to design tolerances. A turbine blade, and a method of rebuilding a portion of a turbine blade, are also disclosed.

  • Patent number: 6162552
    Abstract: A furnace component having a tungsten-based substrate whose surface is protected by a rhenium-based layer in order to render the component less reactive to quartz, glass and other forms of silica. The layer preferably consists essentially of rhenium or rhenium with alloying additions of tungsten. The substrate may be formed of concentric layers of different tungsten-based alloys in order to tailor the physical and mechanical properties of the component. A preferred method of forming the rhenium layer is to wrap the substrate with a rhenium-based wire, and then heat the wire and substrate to sinter and bond the wire to the substrate. Alternatively, the substrate and rhenium layer can be formed by isostatic pressing. Both methods are performed so that the substrate and layer have densities of at least about 96% of their respective theoretical densities.
