Abstract

The regularities of influence of distribution of internal pressures in surface hardened layer of parts after carburizing and hardening are derived. The level of steel contact fatigue hardness is kept during experiments. It was found that extreme changes of compressive internal pressures provokes the pressures concentrators which cause forming of microcracks and that reduces the operational performance of steel.
