METHOD FOR STATIC-IMPULSE SURFACE STRENGTHENING OF SPHERICAL SURFACES Russian patent published in 2009 - IPC B24B39/04 

FIELD: technological processes.

SUBSTANCE: rotary motion is imparted to stock and deforming element fixed on body in the form of stepped holder having larger and smaller steps. Deforming tool is pressed to stock. Deforming element is arranged in the form of ringed pipe fixed at the end of larger step of holder with the possibility of elastic deformation under load and restoration of its size after load clearing. Smaller step of holder is used as wave guide installed in cylinder, to which periodic impulse load is applied by means of striker. Striker and wave guide are arranged in the form of rods of identical diametre. Hydraulic cylinder is connected to hydraulic generator of impulses that generates impulse load.

EFFECT: higher efficiency of treatment, stronger surface of stock with higher hardness, wear resistance and resistance to fatigue wear.
