Abstract: A method is provided for manufacturing at least a portion of a heat exchanger. During this method, a first heat exchanger section is formed that includes a base and a plurality of protrusions. The forming of the first heat exchanger section includes building up at least one protrusion material on the base to form the protrusions. The first heat exchanger section is attached to a second heat exchanger section. A plurality of flow channels are defined between the first heat exchanger section and the second heat exchanger section.

Abstract: Aspects are directed to removing a portion of a component that includes wear to generate a void in the component, where a material of the component has a first microstructure, depositing a filler material in the void, subjecting the filler material to a cold working technique to compress the filler material, and applying a heat treatment to cause the filler material to have a second microstructure that is matched to the first microstructure. Aspects are directed to a case of an engine, including: a first portion with a first material that has a first microstructure, and a second portion with a second material that has a second microstructure, where the second microstructure is matched to the first microstructure, where the second material includes a plurality of layers, and where at least one layer of the plurality of layers includes a compressive residual stress.

Abstract: Aspects are directed to a tribological and creep resistant system configured to operate at temperature in excess of 750° C., comprising: a piston seal that includes a nickel base alloy, where the nickel base alloy includes a Ni3(Al,X) type precipitated phase in an amount greater than 40% by volume. Aspects are directed to a system comprising: a piston seal that includes a cobalt-based alloy. Aspects are directed to a method comprising: heat treating an ingot of a nickel base alloy that includes coarsening a precipitated phase to facilitate forging or wrought forming the ingot, machining the ingot to include a substantially flat surface, and processing the ingot to generate a piston seal.

Abstract: A method of repairing defects in a casting formed from non-weldable or difficult-to-weld alloys is disclosed. The method includes removing the defect from the casting thereby forming a cavity in the casting, placing a filler material in the cavity and fusion welding the filler material in the cavity. The fusion welding produces surface cracks on the casting and sub-surface cracks in the casting. The method then includes brazing at least some of the surface cracks on the casting and processing the casting with a hot isostatic pressure (HIP) process to close at least some of the sub-surface cracks in the casting.
