Abstract: A method and device for the surface peening, especially ultrasonic shot-peening, of at least one partial element of a component of a gas turbine, is disclosed. The partial element, e.g., a sealing fin, and at least one surface of a vibration device impinging the blasting material are positioned relative to each other at an angle between 70° and 90° based on the direction of extension of the sealing fin.

Abstract: A device for surface peening, in particular for ultrasonic shot peening, of a component of a gas turbine, having at least one vibration device that includes a surface that impinges the blasting material, and having a holding device by which a surface area of the component can be positioned relative to the surface of the vibration device, the surface of the vibration device being subdivided into at least two adjacent partial surfaces, each including an overlapping part by which a part of the surface area of the component can be treated by blasting material impinged both by the one and by the other partial surface.

Abstract: A sonotrode for accelerating shot for ultrasonic shot peening, includes at least one vibration exciter and a cover element that has an output side of the sonotrode, wherein the cover element is to be operated by means of the vibration exciter with a forced vibration such that the value of the vibration amplitude of the cover element corresponds essentially to the value of the vibration amplitude of the vibration exciter, where from this cover element another cover element is set out on the further side of the vibration exciter and in which between these two cover elements is stretched a majority of spring elements in the form of tension springs.

Abstract: The present invention relates to a method for the surface peening, in particular for the ultrasonic shot peening, of component (10), in particular of a gas turbine, wherein at least one partial region (12) of the surface of the component (10) is strengthened by applying a blasting agent comprising a plurality of individual blasting particles (56, 58), wherein a blasting agent is used the blasting particles (56, 58) of which have at least two different particle sizes and/or are made of at least two different materials. The invention further relates to such a blasting agent for surface peening.
