Abstract (en)
[origin: EP1568442A1] The method involves transforming a laminar gas flow transporting a blasting shot in a channel (9) of a nozzle (1) into a turbulent flow in an ejection zone (4) of the nozzle. The transformation is such that paths of particles of the shot are random and incident with respect to surface of walls of a cavity to be peened. The laminar gas flow is then directed in an opening (10) of the cavity. An independent claim is also included for a nozzle device of implementing a method of shot peening inner walls of a cavity.
