Method for the ultrasonic peening of large sized annular surfaces of thin parts

摘要

A method of so-called “ultrasonic” peening is described for peening large sized annular surfaces on thin parts. The method uses a microbead mist vibrated in a chamber with an opening so that the surface that is to be peened makes at least five movements past the opening of the peening chamber during peening so as to reduce deformation of the part.
