Abstract: A blade repair method is provided and includes operating a deposition head to deposit additional materials onto base materials while moving the deposition head relative to the base materials, arranging a temperature regulating assembly to remain aside the base materials in a trailing position relative to the deposition head and controlling operations of the temperature regulating assembly during deposition head movements and during depositional operations of the deposition head to control temperatures of at least the base materials and the additional materials during at least the deposition head movements and the depositional operations.

Abstract: A blade repair apparatus is provided and includes a deposition head which is movable relative to base materials and configured to execute a repair operation that includes a deposition of additional materials onto the base materials during deposition head movements, a temperature control system including a temperature regulating assembly coupled with the deposition head in a trailing position and a controller. The controller is operably coupled to the deposition head and the temperature control system. The controller is configured to control the deposition head movements and depositional operations of the deposition head. The controller is configured to control the temperature control system such that the temperature regulating assembly controls temperatures of at least the base materials and the additional materials during at least the deposition head movements and the depositional operations.

Abstract: A method for repairing a fuel nozzle guide includes mechanically separating a heat shield of a damaged fuel nozzle guide from an inner portion of the fuel nozzle guide, manufacturing a replacement heat shield for the damaged fuel nozzle guide, and joining the replacement heat shield to the inner portion of the fuel nozzle guide.

Abstract: A stinger for a cathodic arc vapor deposition system includes a head with a reduced area contact interface.

Abstract: Shot sleeves for high temperature die casting include a nickel-based alloy having a low modulus single crystal with axi-symmetric orientation.

Abstract: A die casting plunger tip includes a hollow outer portion and a hollow inner portion. The outer portion has a first closed end. The inner portion has a second partially closed end. The inner portion is disposed within the outer portion and the second partially closed end is adjacent the first closed end of the outer portion in an axial direction. A plurality of connectors connects the outer portion and the inner portion. A plenum is formed between the outer portion and the inner portion.

Abstract: A metallic test specimen (20) extends along a central longitudinal axis (500) between a first end (22) and a second end (24). The specimen has a first mounting section (30) and a section mounting section (32). A narrowed gauge section (34) is between the first mounting section and the second mounting section. The first mounting section and the second mounting section each have a blind compartment (44) extending longitudinally inward to a closed end (46).

Abstract: A forging die and tooling stack consist of a top and bottom die set positioned on a pusher plate in a die holder. Prior art die and tooling stack designs with rectangular axial cross sections concentrated loading toward the radial center of the stack. By contouring the top surface of the pusher plate and the bottom surface of the die holder, loading at the bottom of the stack can be redistributed to reduce non-uniform loading of components beneath the stack in the load train.

Abstract: Apparatus and methods are provided for cooling workpieces. A cooling gas is directed toward a surface of a workpiece. The workpiece is moved relative to the flow of cooling gas. The cooling gas may include at least a first component that is gaseous at a reference ambient condition and a second component that is a liquid at the ambient condition. The second component may be delivered as a gas or as droplets.
