Abstract
Method for repairing a gas turbine component, which at least at the spot to be repaired consists of a ceramic composite material, where an energy beam locally heats the gas turbine component in a zone, and where one or more auxiliary materials and optionally fibers and/or particles are fed to this zone, wherein a ceramic is generated in the melting zone through the one or more auxiliary materials, and, optionally, the one or more auxiliary materials together with the fibers and/or particles forms a ceramic composite material.
