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&#xb0; and 90&#xb0; based on the direction of extension of the sealing fin.

Method and device for the surface peening of a partial element of a component of a gas turbine

The invention relates to a peening chamber for surface peening, in particular for ultrasonic shot peening of gas turbine components (), which, at least with a component region () comprising the surface to be treated, are to be arranged within a chamber wall (), which spatially defines the peening chamber, wherein at least one wall region () of the chamber wall () is designed to be adjustable in order to vary the geometry of the peening chamber.
