Diffusion braze repair of metal components

摘要

A method for repairing a metal component having a crack, the method comprising depositing (14) a brazing material into the crack of the metal component, and exposing the metal component to a plurality of heating cycles (16, 18, 20). Each successive heating cycle has a temperature that is less than a temperature of a previous heating cycle, and a duration that is at least as long as a duration of the previous heating cycle. The plurality of heating cycles comprises an initial heating cycle (16) having a temperature sufficient to at least substantially melt the brazing material within the crack.
