Abstract
The process of laser hardening of 42KhN2MA steel samples using continuous radiation and transverse beam vibrations at a frequency of 223 Hz has been considered. The influence of processing modes on the response parameters of the system and the depth and width of the laser quenching regions has been determined. It has been shown that the use of transverse beam vibrations increases the microhardness, the area of the hardened layer, and its uniformity and preserves the geometric shape of the slot profile compared to processing with a defocused beam. The wear resistance of the laser-hardened regions is significantly higher than the base material.
