Abstract: Concepts for fabricating improved cores for investment casting are described. The cores are composite which include refractory metal elements (200) and ceramic elements (120). The refractory metal elements are provided to enhance the mechanical properties of the core and/or to permit the fabrication of cores having shapes and geometries that could not otherwise be achieved. In one embodiment, the entire core may be made of refractory metal components. The cores may be used to investment cast gas turbine superalloy components.

Abstract: Corrosion and oxidation resistant, high strength, directionally solidified superalloy alloys and articles are described. The articles have a nominal composition in weight percent of about 12% Cr, 9% Co, 1.9% Mo, 3.8% W, 5% Ta, 3.6% Al, 4.1% Ti, 0.015% B, 0.1 % C, up to about 0.02 Zr, balance essentially nickel, and include no intentional additions of hafnium or zirconium, and also have a small amounts of tantalum carbide. The resultant articles have good hot corrosion resistance and superior oxidation resistance and creep properties. The articles are preferably columnar grain, but may also be single crystal.

Abstract: The invention includes melting a filler material into a metallic substrate having a defect under conditions chosen to preclude cracking. In a preferred embodiment of the invention, a laser beam is operated at a relatively low power density and at a relatively large diameter for an extended length of time to produce a molten pool with a low aspect ratio.

Abstract: The invention concerns a thermal barrier coating system (12) requiring no bond coat adherence high temperature heat treatment and having enhanced insulating capabilities such that it may be applied to gas turbine engine components of varied shape, thickness and size. In preferred embodiments, the system includes a metallic bond coat which does not require a bond coat adherence high temperature heat treatment to form a bond between the metallic bond coat and a metallic substrate to which it is applied. A porous ceramic insulating layer is deposited on the metallic bond coat. In another preferred embodiment, the porous ceramic insulating layer is deposited directly on the metallic substrate. The coating system is particularly advantageous for insulating metallic components prone to distortion in heat treatment and those requiring insulation in an as machined condition.
