Patent number: 11235405Abstract: A method of repairing a superalloy component includes subjecting the superalloy component, including a repair area, to a phase agglomeration cycle, which includes stepped heating and controlled cooling of the component. The method further includes applying weld material to the repair area to create a weld surface; and covering the weld surface with brazing material. The component is then subjected to a braze cycle to produce a brazed component. The brazed component is cleaned, and the cleaned component is subjected to a restorative heat treatment to restore the microcrystalline structure and mechanical properties of the component.Type: GrantFiled: May 2, 2019Date of Patent: February 1, 2022Assignee: General Electric CompanyInventors: Brian Leslie Henderson, Paul Albert Cook, Yan Cui, Daniel James Dorriety
