Abstract

A method for repairing a component such as a turbine blade is provided. At the end of its operating time, the component has, for example, a depletion of aluminium in a region near the surface. The application of a repair layer is provided including particles with an increased proportion of aluminium. A subsequent heat treatment may achieve the effect of equalizing the concentration of aluminium between the repair layer and the region near the surface, and so the aluminium content required for new components is achieved again.
