摘要： A method of fabricating a Ti-6Al-4V titanium alloy component including solution heat treating a forged Ti-6Al-4V titanium alloy component at a temperature within the alpha+beta two-phase field for the material of the component for a predetermined period of time, and subsequently cooling the component. The component is then age heat treated using an overaging process at a predetermined overaging temperature for a predetermined time, and the component is cooled to room temperature. The overaging temperature is selected to be a higher temperature than an aging heat treatment temperature for effecting a maximum yield strength in the component.

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 component (10) including a substrate material (12) and a wear alloy coating (14) applied to the substrate 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/or 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： A method for preparing a protective layer (38) on a surface of the substrate (36) that requires a bonding temperature (BT) above a detrimental phase transformation temperature range (28) of the substrate, and then cooling the layer and substrate without cracking the layer or detrimentally transforming the substrate. The protective layer (38) and the substrate (36) are cooled from the bonding temperature (BT) to a temperature (46) above the detrimental phase transformation range (28) at a first cooling rate (30) slow enough to avoid cracking the protective layer. Next, the protective layer and the substrate are cooled to a temperature below the detrimental phase transformation range of the substrate at a second cooling rate (27) fast enough to pass the detrimental phase transformation range before a substantial transformation of the substrate into the detrimental phase can occur.

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 method of adding material to a nickel-based superalloy component, such as a gas turbine rotor disk, without damaging the underlying material and without creating an unacceptable level of cracking. The method is advantageously applied in the repair of Alloy 706 turbine rotors having experienced operating failures in the steeple region of the disk. Once the damaged material is removed, replacement nickel-based superalloy material is added using a welding process that protects both the underlying material and the replacement material. The replacement material may be added by welding, with the preheat temperature maintained no lower than 100° C. below the aging temperature of the deposited alloy and with the interpass temperature maintained below the solution annealing temperature of the alloy. Alternatively, the replacement material may be preformed and welded to the original material using a friction welding process. In one embodiment, a replacement steeple of directionally solidified or single crystal material is installed onto a disk hub using a linear friction welding technique.
