All rights reserved.Experiments in defocus of beam rectangular-shaped fiber laser in the range of 30-65 mm. using a full factorial experiment, we constructed the surface to depth and width of the zone of hardening through varying the speed of the beam in the range of 15-20 mm/s, power 3-4 kW. Comparative wear tests have shown that laser hardening with a rectangular spot reduces the number of tempering zones and increases the wear resistance of 40Cr steel by 25-35% compared to hardening with a round spot.
