Abstract (en)
The method involves coating a turbine blade (40) with a protective layer (54) and a recess is inserted in a blade vane (48) of a blade (42) of the turbine blade for adjusting the resonance frequency of the turbine blade. The recesses are introduced after coating of the turbine blade. An independent claim is also included for a blade ring for a rotor of a turbine with axial flow.
Abstract (de)
Die Erfindung betrifft ein Verfahren zum Herstellen einer beschichteten Turbinenlaufschaufel (40), wodurch deren Frequenzeigenschaft besonders einfach an die erforderlichen Randbedingungen angepasst werden kann. Hierzu ist vorgesehen, dass das Einbringen von Ausnehmungen in eine Schaufelspitze (4) des Schaufelblatts (42) der Turbinenschaufel (40) nach dem Beschichten der Turbinenlaufschaufel (40) erfolgt.
