Способ упрочнения стальных деталей, включающий термическую обработку, холодную пластическую деформацию и азотирование, отличающийся тем, что, с целью повышения прочностных свойств сердцевины детали за счет эффекта субструктурного упрочнения, перед азотированием проводят последеформационный отпуск в интервале температур, на 80-120oC превышающих температуру отпуска, обеспечивающую максимальную твердость.A method of hardening steel parts, including heat treatment, cold plastic deformation and nitriding, characterized in that, in order to increase the strength properties of the core of the part due to the effect of substructural hardening, post-deformation is carried out before nitriding in a temperature range of 80-120 o C higher than the temperature tempering for maximum hardness.
