Abstract (en)
[origin: EP1772228A1] The method for repairing gas turbine base material component (406), comprises cleaning the repairing place, filling the repairing place (420) with filler material composition and carrying out heat treatment in the area of repairing place. The filler material exhibits micro- and/or nanoscale particle. The gas turbine base material component is arranged with a microstructure. A measurement for preventing the oxidation of the filler material, is taken in the filling of the repair place. The filler material exhibits two material components with a eutectic mixture ratio. The method for repairing gas turbine base material component (406), comprises cleaning the repairing place, filling the repairing place (420) with filler material composition and carrying out heat treatment in the area of repairing place. The filler material exhibits micro- and/or nanoscale particle. The gas turbine base material component is arranged with a microstructure. A measurement for preventing the oxidation of the filler material, is taken in the filling of the repair place. The filler material exhibits two material components with a eutectic mixture ratio. The temperature and hold time of the heat treatment are coordinated on the filler material composition and the base material component that results an epitaxial binding of the filler material takes place at the surrounding base material. A cool gas injecting method (426) is used for filling the repairing place and enables low temperature of the injected particles. The particles are surrounded by a covering that is developed from the base material component, when filling the repairing place. A fracture in the base material (420) is repaired in such a manner that a fracture end is filled with micro or nanoscale particle.
