METHOD OF STATIC-PULSE WORKING BY SURFACE PLASTIC DEFORMATION Russian patent published in 1997 - IPC

FIELD: technique of finishing-hardening working of parts from steel and alloys by surface plastic deformation. SUBSTANCE: plastic deformation is accomplished by tool to which constant static load and periodic pulse load are applied normally to treated surface. Periodic pulse load is applied by means of striker and waveguide. Mathematical relations are offered for determination of shape, amplitude, duration and frequency of single pulses of deformation force. EFFECT: higher efficiency. 3 cl, 2 dwg, 1 tbl
