An apparatus (1) for shot peening of blade mounting areas (51) on a disc (53) of a rotor arrangement (55) is presented, comprising a peening nozzle unit (5) which is operatively connectible with a movement device (3), and which allows the streaming of a shot peening media (9) along a longitudinal axis (25). The peening nozzle unit comprises a nozzle outlet (15) which extends at least partially in circumferential direction of the peening nozzle unit, and a deflection arrangement (17, 83) with a deflection area (39, 85) for the shot peening media (9). The deflection area is at least partially cone or half-hyperboloid shaped over at least a part of the circumferential direction of the peening nozzle unit, such that shot peening media streaming in direction of the longitudinal axis (25) of the peening nozzle unit is passing the nozzle outlet (15) over an angle range in circumferential direction after being deflected by the deflection arrangement (17, 83). Further, a method for shot peening of blade mounting areas (51) on a disc (53) of a rotor arrangement (55) is presented, wherein a peening nozzle unit (5) of an apparatus (1) for shot peening is positioned in a slot profile of the respective blade mounting area (51), and is controlled guided along the contour of the slot profile with a nozzle outlet (15) facing the contour of the slot profile such that the contour of the slot profile is at least approximately uniformly peened. |
