Abstract:
1. A method for surface peening of a partial element of a component of a gas turbine, comprising positioning the partial element relative to a surface of a vibration device, wherein the vibration device impinges blasting material, wherein the surface of the vibration device and the partial element are positioned relative to each other at an angle between 70° and 90° based on a direction of extension of the partial element, and wherein the partial element is a sealing fin; wherein the sealing fin is surface peened in a first peening chamber that includes the vibration device, wherein boundary walls of the first peening chamber are arranged substantially parallel to the direction of extension of the sealing fin; and wherein a rotor blade of the component is arranged in a second peening chamber that is adjacent to the first peening chamber, wherein one of the boundary walls of the first peening chamber is a side boundary wall of the second peening chamber.
