摘要：
The invention relates to a method for repairing a component such as a turbine blade. At the end of its operating time, said component has, for example, a depletion of aluminium in a region (12) near the surface, the invention providing the application of a repair layer (19) containing particles (18) with an increased proportion of aluminium. A subsequent heat treatment can achieve the effect of equalizing the concentration of aluminium between the repair layer (19) and the region (12) near the surface, and so the aluminium content required for new components is achieved again. The component consequently has advantageous properties that are almost equivalent to those of a new component.
