Abstract (en)
The method involves introducing a cleaning agent (12) into a hollow space (9), which contains a surface of a gas turbine blade (8). The blade is arranged in a radiation chamber (19). The cleaning agent is accelerated as mechanical abrasive on the surface within the hollow space and/or along the surface. The surface is chemically cleaned and/or de-stratified. The cleaning agent in the hollow space is sucked by producing low pressure in and/or at the hollow space. Contaminated mechanical abrasives are removed by suction. An independent claim is also included for a device for treating a surface of a turbine blade.
