The paper examines the results of micrographic and tribotechnical tests of chisel steel X12 in a friction pair with the through hardened steel 40X when lubricated with the industrial oil I20. It is shown that the use of lateral oscillations of the laser beam significantly increases the processing productivity. It has been established that the high-quality laser thermohardening of sample edges is possible only by applying lateral oscillations of the beam when exposed to the continuous laser radiation. In the case of optimal laser processing conditions and hardening of 50% of the sample friction surface, the wear resistance properties have been increased by 1.6 times compared to the through hardening.
