Abstract: A method for forming a hollow component includes injecting a fluid into an internal cavity of the hollow component to achieve a pressure of the fluid within the internal cavity that is greater than an ambient pressure. The method further includes drilling at least one hole through the hollow component from an external surface of the hollow component to the internal cavity by applying a laser beam to the hollow component with a laser generator. The method further includes directing the fluid from the internal cavity and through the at least one hole so as to exit the hollow component via the at least one hole.

Abstract: An apparatus for finishing a component includes at least one articulating arm having a shot peening apparatus and at least one laser source. A plurality of laser redirectors are configured to redirect a laser originating from the laser source. Each laser redirector in the plurality of laser redirectors is mounted to a first rail and a second rail. A controller is controllably coupled to the articulating arm and each of the rails such that output signals from the controller control a position of the articulating arm, and a position of each laser redirector in the plurality of laser redirectors.

Abstract: A method for treating a substrate prior to metallic coating includes the steps of providing a substrate having a surface to be coated and at least one contaminant selected from as-delivered organics and post-burn out oxides on the surface; treating the surface with a laser to remove the at least one contaminant to produce a cleaned surface on the substrate; and applying a metallic coating to the cleaned surface. Grit blasting can be avoided, and reverse arc transfer cleaning is avoided or minimized, resulting in time savings and less stress on the substrate.

Abstract: A method of removing scale from a casting may include positioning the casting relative to a laser emitter. The casting may comprise a superalloy and the scale may have formed on the surfaces thereof, with the scale being a byproduct of a method of manufacturing the casting. The method may also include passing a laser beam emitted from the laser emitter across the casting such that the laser beam causes the scale to at least one of crack, break, shatter, and spall. The superalloy may be a nickel-based superalloy and the scale may include a metal carbide layer.

Abstract: A method for stripping ceramic from a component includes applying a liquid to a ceramic coating of an outer surface of the component. The method also includes directing a plurality of laser pulses at the ceramic coating with the applied liquid in order to spall the ceramic coating from the component.

Abstract: A method for coating a part according to an aspect of the disclosure includes the step binding a metallic powder to a section of the part. The metallic powder is then energized which at least partially melts and resolidifies the metallic powder to form a first metallic coating. After the first layer of metallic coating is formed a second layer of metallic coating is deposited on substantially all of the part.

Abstract: A method for treating a surface of a contoured titanium substrate used for adhesively bonded engine components. The method including applying energy from a fiber laser system to a contoured surface of a titanium substrate, the laser energy is distributed to the contoured titanium surface by at least one of direct light of sight, reflection, or scattering of one or more laser beam.
