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...

| description | 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 of the tool pressing to the part 25-100 N.EFFECT: increased thickness of the hardened layer of the part, and increased microhardness of its surface layer.2 cl, 1 tbl
Изобретение относится к области технологии машиностроения, а именно к упрочнению поверхностного слоя стальных деталей. Осуществляют низкотемпературное азотирование детали, а затем проводят ее поверхностное пластическое деформирование. Поверхностное пластическое деформирование детали осуществляют ультразвуковым инструментом при частоте f=19-22 кГц и амплитуде ξ=2-20 мкм акустических колебаний и усилием его прижима к детали 25-100 H. В результате увеличивается толщина упрочненного слоя детали и повышается микротвердость ее поверхностного слоя. 1 з.п. ф-лы, 1 табл. |
