Abstract

The article reflects the results of the study of the process of hardening of steels radiation fiber laser and the increase of productivity of process of laser hardening due to implementation of fiber-optic lasers instead of CO₂ and the increase of the coefficient of absorption of laser radiation and the exclusion of the necessity to use absorbing coating. The research studied the structure of the hardened layer, compared with the structure of the obtained on CO₂ laser, and presented practical results of hardening fiber laser.
