Abstract: Methods of forming a desired geometry at a location on a superalloy part are disclosed. The method may include directing particles of a powder mixture including a low melt temperature superalloy powder and a high melt temperature superalloy powder to the location on the superalloy part at a velocity sufficient to cause the superalloy powders to deform and to form a mechanical bond but not metallurgical bond to the superalloy part. The directing of particles continues until the desired geometry is formed. Heat is applied to the powder mixture on the repair location. The heat causes the low melt temperature superalloy powder to melt, creating the metallurgical bonding at the location. Another method uses the same directing to form a preform for repairing the location on the part. The low melt temperature superalloy powder melts at 1287° C.

Abstract: A process of modifying a passage in a component is provided. The process includes inserting a first material into the passage; blocking at least one end of the passage; inserting an elongated member into the passage through the first material; heat treating the passage, the first material, and the elongated member to form a solid interior in component; and machining through the solid interior to form a modified passage in the component.

Abstract: A closure element for an internal passage in a component, and a related method and turbine blade or nozzle are disclosed. The closure element includes a spherical body made of a first superalloy, and a plurality of extensions extending from a surface of the spherical body. The plurality of extensions made of the same, similar or different material other than the first superalloy. Subjecting the component to at least one thermal cycle causes a braze material to form a metallurgical bond with the spherical body, the plurality of extensions and the passage wall to seal the internal passage.

Abstract: A method for repairing a part and the resulting is disclosed. The method includes positioning a plug having an inner braze element coupled thereto into a cavity defined by an internal surface of a component. The cavity has a circular cross-section at the external surface of the component. The plug completely fills the circular cross-section and the inner braze element is within the cavity. A braze paste is positioned at least partially around the plug at the external surface. The component is positioned such that the inner braze element is above the plug. The component is subjected to a thermal cycle to melt the inner braze element around the plug, completely sealing the cavity by forming a metallurgical bond with the plug and the internal surface of the component. During the thermal cycle the braze paste is melted to form a metallurgical bond with the plug and external surface.
