METHOD OF SURFACE LAYER HARDENING OF STEEL PARTS

FIELD: machine building.SUBSTANCE: low temperature part nitrogen hardening, and then its surface plastic deformation are performed. The surface plastic deformation of the part is performed by the ultrasound tool at frequency f=19-22 kHz and amplitude ?=2-20 mcm by the acoustic oscillations and force...
