Publication number: US20220186381A1
Application number: 17/551,480

Abstract:
A method may include cold spraying a masking material on selected locations of a component to form a masking layer, wherein the masking material comprises a metal or alloy; additively manufacturing an additively manufactured portion of the component at locations at which the masking layer is not present; and removing the masking layer from the component. The masking layer may be configured to protect portions of the component by covering or otherwise providing a physical barrier that reduces or prevents material from adhering to unwanted portions of the component during a subsequent manufacturing and/or repair technique. Additionally, the masking layer may be reflective to infrared radiation and/or intimately contact the component and function as a heat sink or thermally conductive layer to transfer heat from the component.

Publication number: US20220161326A1
Application number: 17/534,111

Abstract:
In some examples, systems and techniques for repairing or otherwise forming a blade of a bladed disk. In one example, a method including positioning a shield member around a perimeter of a partial blade extending from a rotor disk of a bladed disk, the shield member being positioned adjacent to a build surface of the partial blade; and depositing, with the shield member around the perimeter of the partial blade, a material on the build surface using an additive manufacturing technique to form a repaired portion on the build surface of the partial blade.

Publication number: US20220161364A1
Application number: 17/533,664

Abstract:
An additive manufacturing system may include an energy delivery device configured to deliver energy to a component to form a melt pool at least partially surrounded by a cooling region; and an optical system comprising: an imaging device; and an occulting device, wherein the occulting device is configured to occult at least part of thermal emissions produced by the energy and the melt pool and transmit at least some thermal emissions produced by the cooling region.
