Method and apparatus for improving the wear characteristics of the component of a gas turbine

The invention relates to a method for improving a gas turbine of the wear properties of a component (10), wherein at least one surface region (22, 24, 26, 28, 30) of the component (10) is at least locally treated, comprising the steps of: - positioning of the surface area to be machined (22, 24, 26, 28, 30) of an associated tooth system (14) of the component (10) and a corresponding, grit impinging surface (48) of a vibration device (44) relative to each other and - surface peening, in particular ultrasonic shot peening, the surface area (22, 24, 26, 28, 30) of the associated tooth system (14). Moreover, the invention relates to a device for surface peening, in which the surface (48) of the vibrator (44) and to be peened surface area (22, 24, 26, 28, 30) a toothing (14) of the component (10) by means of the holding means (60) are positionable relative to each other.
