Abstract: A method for forming a metallic structure having a secondary component includes positioning the secondary component on a main formation surface of a main tool, the main formation surface corresponding to a desired shape of a first layer of material. The method also includes depositing a layer of material on the secondary component and the main formation surface using a cold-spray technique such that the layer of material bonds to the secondary component. The method also includes removing the layer of material and the secondary component to form the metallic structure.

Abstract: A method for forming a metallic structure having multiple layers includes providing a main tool having a main formation surface corresponding to a desired shape of a first layer of material. The method also includes depositing the first layer of material on the main formation surface using a cold-spray deposition technique. The method also includes positioning a secondary tool having a secondary formation surface in a portion of a first volume defined by a first surface of the first layer of material. The method also includes depositing a second layer of material on the secondary formation surface using the cold-spray deposition technique. The method also includes removing the secondary tool such that the first volume is positioned between the first layer of material and the second layer of material.

Abstract: Systems and methods are disclosed herein for repairing components. A material layer may be deposited on a surface of a component. The material layer may cover a cooling hole. A pulsed heat source may heat the component and the material layer. An infrared camera may take a series of images of the component. A location of the cooling hole may be identified based on thermal properties of the component. A removal tool may remove a portion of the material layer in order to expose the cooling hole.

Abstract: A method for forming a reinforced metallic structure includes depositing a mixture of metallic particles and reinforcing particles on a formation surface of a tool by cold-spraying the metallic particles to form a layer of mixed material, the formation surface corresponding to a desired shape of the reinforced metallic structure. The method also includes removing the layer of mixed material from the formation surface to create the reinforced metallic structure

Abstract: A method of evaluating and validating additive manufacturing operations includes generating a multidimensional space defined by a plurality of bounds, each of the bounds being defined on a distinct parameter of an additive manufacturing process and each of the parameters being directly related to the occurrence of a horizontal lack of fusion flaw, each of the parameters being a dimension in a multi-dimensional coordinate system, determining a coordinate position of at least one additive manufacturing operation within the multi-dimensional coordinate system, and categorizing the operation as free of horizontal lack of fusion flaws when the coordinate position is within the multi-dimensional space.

Abstract: A nickel-chromium (Ni—Cr) alloy and a method for electrodepositing the Ni—Cr alloy on a turbine engine component for dimensionally restoring the engine component are described. The engine component is restored by re-building wall thickness with the Ni—Cr alloy including from 2 to 50 wt % chromium balanced with nickel. The turbine component coated with the Ni—Cr alloy is heat-treated at a high temperature to homogenize composition of the alloy to mimic the base alloy and to restore materials lost during repair of the turbine component.
