Abstract: A coating method for a component with at least one aperture includes providing a component having at least one aperture formed in a surface thereof; additively manufacturing a hollow member on a portion of the surface to define a space above each aperture, the portion of the surface being adjacent to the aperture, the hollow member having an inner peripheral geometry complementary to a peripheral geometry at least one of aperture; applying at least one coating over the surface of the component and around hollow member to form an applied coating having an applied coating thickness; and removing at least a portion of the hollow member to make a top portion of the hollow member coplanar with the applied coating to expose the space through the applied coating; wherein a lower portion of the hollow member remains to define the space through the applied coating.

Abstract: This disclosure provides systems, methods, and tooling for additive manufacturing on a build surface of a pre-existing component. An additive manufacturing tool successively positions layers of powdered materials and selectively fuses the layers of powdered materials to create an additive component on the build surface of the pre-existing component. The pre-existing component is secured in a build plate by a thermal expansion fit during the additive manufacturing process.

Abstract: A method of manufacturing a metal object by selective melting of a metal powder is provided. The method includes forming the metal object layer by layer in a metal powder bed on a retractable build platform. During the forming, a metal sleeve is provided spaced apart from and substantially paralleling an outer surface of the metal object, the metal sleeve being separated from the metal object by a gap filled with non-melted metal powder. The metal sleeve reduces thermal distortions in the object. An additive manufacturing system that includes a metallic sleeve that surrounds the metal object as it is formed is also disclosed.

Abstract: A method for correction of thermal defects using tomographic scanning for additive manufacturing is provided. The method may include forming a portion of an object using an additive manufacturing system based on an intended three-dimensional (3D) model of the object that is in an additive manufacturing system format. The portion of the object is scanned using a tomographic scanner to obtain a model of the portion of the object in a tomographic scanner format. The model is converted from the tomographic scanner format into the additive manufacturing system format to obtain a converted tomographic model; and the converted tomographic model is compared to the intended 3D model to identify a defect in the portion of the object. A modified 3D model may be generated of the object correcting the intended 3D model to address the defect of the portion of the object.

Abstract: The present disclosure is directed to an impingement insert for a gas turbine engine. The impingement insert includes an insert wall having an inner surface and an outer surface spaced apart from the inner surface. A nozzle extends outwardly from the outer surface of the insert wall. The nozzle includes an outer surface and a circumferential surface. The insert wall and the nozzle collectively define a cooling passage extending from the inner surface of the insert wall to the outer surface of the nozzle. The cooling passage includes an inlet portion, a throat portion, a converging portion extending from the inlet portion to the throat portion, an outlet portion, and a diverging portion extending from the throat portion to the outlet portion. The cooling passage further includes a cross-sectional shape having a semicircular portion and a non-circular portion.

Abstract: A test feature is disclosed that is formed during metal powder additive manufacturing of a production part. The test feature may include a metal powder sample capsule including a chamber for capturing unfused powder from the metal powder additive manufacturing, and a removable cap closing an end of the chamber. Alternatively, a test feature may include a quality control (QC) part, and at least one additional test element including a metal powder sample capsule integrally coupled to the QC part and including a chamber for capturing unfused powder from the metal powder additive manufacturing. The QC part is identical to the production part excepting the at least one test element. The QC part and the at least one test element are formed during the same metal powder additive manufacturing as the production part.

Abstract: Particle detection systems are disclosed. The particle detection system may include a conduit configured to receive particles removed from a component, and at least one sensor positioned adjacent the conduit. The at least one sensor may be configured to detect a particle characteristic for the particles in the conduit removed from the component. The particle detection system may also include a particle analysis system in communication with the at least one sensor. The particle analysis system may be configured to analyze the particle characteristic for the particles in the conduit to determine if the component is substantially free of particles.
