Verfahren zur Entschichtung von Triebwerksbauteilen und Vorrichtung zur Durchführung des Verfahrens

摘要

Method for selective removal of surface layers from an engine component, especially a turbine blade of a high performance turbine, using high energy radiation the wavelength of which is short enough to supply enough energy for layer removal. The material removal energy threshold is exceeded in the areas where material is to be removed, whereas in material that it is to be retained it is not. A spectrometer (20) is linked by an optical fiber (22) to the machining area and a control unit employs the spectroscopic values in a self-regulating process. The invention also relates to a corresponding device.
