摘要： A fusion weldable superalloy containing 0.005-0.5 wt. % scandium. In one embodiment, the superalloy may have a composition similar to IN-939 alloy, but having added scandium and having only 0.005-0.040 wt. % zirconium. A gas turbine component may be formed by an investment casting of such a scandium-containing superalloy, and may include a fusion weld repaired area. A scandium-containing nickel-based superalloy coated with an MCrAlY bond coat will have improved cyclic oxidation resistance due to the sulfur-gettering effect of the scandium.

摘要： A cold spray process (20) for applying an abradable coating (16) to a substrate material (12). A bond coat layer (14) and/or an abradable coating material layer (16) are applied to a substrate (12) by directing particles of the material toward the substrate surface at a velocity sufficiently high to cause the particles to deform and to adhere to the surface. Particles of the bond coat material may first be directed toward the substrate surface at a velocity sufficiently high to clean the surface (24) but not sufficiently high to cause the particles to deform and to adhere to the surface.

摘要： A process (30) for the repair of a component part (36,66) incorporating a cold spray process step (50) for depositing material particles (54) to fill a discontinuity (40) in the part surface (42) or to create a desired surface geometry (78) on the part (66). The cold spray process may be controlled to provide a grit blasting effect prior to depositing the material in order to remove contaminants (48) from the surface of the part. The material deposited (56) by the cold spray process may form a joint (78) between an insert (72) and the part (66). The process may be used to repair parts made of directionally solidified (DS) or single crystal (SC) base material (44) without causing a re-crystallization of the base material. The process may further be used to deposit repair material (56) over a braze material (22).

摘要： A wear alloy coating (14) applied to a substrate material (12) by a cold spray process. Particles of the wear alloy coating material (16) are directed toward a target surface (18) of the substrate at a velocity sufficiently high for the particles to deform and to adhere to the target surface. The size and composition of the particles may be varied during the cold spray process to produce a coating with a varying property across the depth of the coating. Particles of the wear alloy material may be applied by cold spraying along with particles of a second material such as a lubricant or a ceramic material. For Group 5 hard facing materials, the size and distribution of the embedded carbide nodules may be controlled by controlling the selection of the carbide particles being sprayed. The cold spray process permits a wear alloy coating to be applied proximate a brazed joint or over a directionally stabilized or single crystal material without degrading the underlying material.

摘要： An abrasive coating and a process for forming the abrasive coating by co-depositing hard particles within a matrix material onto a substrate using a cold spray process. The cold sprayed combination of hard particles and matrix material provides a coating that is wear, erosion and oxidation resistant. The abrasive coating may have different compositions across its depth. The hard particles may be deposited at different densities across the thickness of the matrix material. A first layer of the abrasive coating proximate the surface of the substrate may be devoid of hard particles.

摘要： A process (20) for applying a thermal barrier coating (51) to a turbine component (50) including the step (34) of depositing a bond coating layer (56) by, directing solid particles using a cold spray process. The layer of bond coating material may have different depths (80,82) in different areas of the component (50), and it may have different compositions (60,62) across its depth. The precise control afforded by the cold spray material deposition step allows the surface of the bond coating material layer to be formed with a predetermined surface roughness or with a plurality of micro-ridges (86) in order to optimize its bond to the overlying ceramic insulating layer (52).

摘要： An airfoil, a method of manufacturing an airfoil, and a system for cooling an airfoil is provided. The cooling system can be used with an airfoil located in the first stages of a combustion turbine within a combined cycle power generation plant and involves flowing closed loop steam through a pin array set within an airfoil. The airfoil can comprise a cavity having a cooling chamber bounded by an interior wall and an exterior wall so that steam can enter the cavity, pass through the pin array, and then return to the cavity to thereby cool the airfoil. The method of manufacturing an airfoil can include a type of lost wax investment casting process in which a pin array is cast into an airfoil to form a cooling chamber.
