A method for the selective removal of one or more layers from a power unit component, e.g., a turbine blade of a heavy-duty turbine, using high-energy radiation of such a wavelength that the supplied energy is so strongly absorbed by the layer to be removed in each case that the removal threshold of the specific material of the layer to be removed is exceeded, while this removal threshold is not reached in the subsurface to be preserved, a spectrometer connected to a control unit via a light-conducting fiber cable such that the method-specific characteristic values are determinable by spectroscopic methods during the removal of the respective layer and are used for the self-regulating process limitation.
A method for selective removal of at least one layer from a component subsurface to be preserved for process-controlled removal of coatings from power unit components, comprising:
