STRUCTURE BRAZE REPAIR OF HARD-TO-WELD SUPERALLOY COMPONENTS USING DIFFUSION ALLOY INSERT

摘要

A method (100) for treating a component (201) and a treated component (201) are provided. The method (100) includes the steps of machining (101) a tapered slot (204) in the component (201). The tapered slot (204) is measured to determine dimensions. An insert (301) is formed to have a corresponding geometry to the tapered slot (204) with a braze gap (303) between an outer surface of the insert (301) and an inner surface of the tapered slot (204). A layer of a braze material is deposited on the outer surface of the insert (301), where a thickness of the layer corresponds to the braze gap (303). The layer of the braze material on the outer surface of the insert (301) is sintered to fabricate a diffusion layer (302). The insert (301) is positioned into the tapered slot (204). The diffusion layer (302) is brazed to join the insert (301) to the taper slot. The treated component (201) includes a surface having a tapered slot (204), an insert (301), and a braze joint.
