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.

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.
