Effect of Laser Strengthening and Beam Defocusing on the Geometrical Parameters of Hardened Zones

  • V. P. BiryukovEmail author
New Technologies in Mechanical Engineering


The paper presents the results of metallographic studies of the geometric parameters of hardened zones depending on the laser processing mode. Based on the results of regression analysis, plots were constructed for surfaces showing the effect of the power, velocity, and transverse oscillations of the beam on the width and depth of hardened zones. High-frequency beam scanning increases the performance of laser hardening by 1.6–2.5 times.
