Abstract:
A method of repairing a defect in a gas turbine engine component includes exposing the defect to a chemically reducing gas to clean the defect surface of undesired particles and oxidation. Before the cleaning, a protective coating is applied to the defect surface to resist inter-granular attack during the cleaning process.
