摘要： A method of regenerating gas-turbine stator vane comprising the steps of: grinding the oxidized layer and the cracks 2 formed at surface portion so that a part of the cracks 2 remains; filling an equivalent material and a brazing material 4 into the ground portion, the equivalent material 3 having an equality with the base material 1 for the stator vane, and the brazing material 4 having a melting point lower than that of the equivalent material 3; heat treating the filled portion under pressurized inert gas atmosphere so as to melt the brazing material; performing brazing treatment by diffusing the molten brazing material into the cracked portions. According to the above method, the stator vane occurred with material deterioration and damages or the like due to operation of a gas turbine can be efficiently regenerated to provide a high quality without requiring to completely grinding and removing the cracks including a closed crack formed at surface of the stator vane.
