SUPERALLOY PART AND METHOD OF PROCESSING

A method for repairing a part and the resulting is disclosed. The method includes positioning a plug (50) having an inner braze element (52) coupled thereto into a cavity (46, 204) defined by an internal surface of a component (40). The cavity (46, 204) has a circular cross-section at the external s...

Zusammenfassung:	A method for repairing a part and the resulting is disclosed. The method includes positioning a plug (50) having an inner braze element (52) coupled thereto into a cavity (46, 204) defined by an internal surface of a component (40). The cavity (46, 204) has a circular cross-section at the external surface (42) of the component (40). The plug (50) completely fills the circular cross-section and the inner braze element (52) is within the cavity (46, 204). A braze paste (56, 58) is positioned at least partially around the plug (50) at the external surface (42). The component (40) is positioned such that the inner braze element (52) is above the plug (50). The component (40) is subjected to a thermal cycle to melt the inner braze element (52) around the plug (50), completely sealing the cavity (46, 204) by forming a metallurgical bond (59, 66) with the plug (50) and the internal surface of the component (40). During the thermal cycle the braze paste (56, 58) is melted to form a metallurgical bond (59, 66) with the plug (50) and external surface (42).
