| 摘要 |
The invention relates to a method and an apparatus for the surface blasting, especially for the ultrasonic shot peening, of gas turbine blades in the area of their blade roots. The apparatus encompasses at least one vibrator, especially at least one ultrasonic sonotrode ( 12 ), comprising an oscillating surface ( 13 ), whereby the or each vibrator is oriented in such a manner so that the oscillating surface ( 13 ) of the or each vibrator extends essentially in the horizontal direction, whereby a processing chamber ( 14 ), for receiving the or each blade root ( 15 ) to be processed, adjoins the or each oscillating surface ( 13 ). According to the invention, the processing chamber ( 14 ) is embodied in such a manner so that the or each gas turbine blade ( 11 ) is orientable in such a manner for the surface blasting so that during the blasting at least one profiled support surface, which is to be processed, of the or each blade root ( 15 ) extends at least temporarily essentially parallel to the oscillating surface ( 13 ) of the or each vibrator, especially the or each ultrasonic sonotrode.
