| Abstract: | Repair brazing of the first and the second stage vanes of nickel base superalloy was studied. It was concluded that the oxide film could be removed from the crack in vanes with fluoride or machining method, properties of the vane repair brazed with block and powder alloy in the crack after cleaning oxide film were satisfied, and the vane passed 100h turbojet test run. |
