Abstract: We consider the technology is complex, the volume and surface hardening steel 38ХН3МФА. The effect of laser radiation on a steel 38ХН3МФА with different initial bulk thermal treatment using the method of mathematical planning of experiments. Drive technology volumetric heat treatment and laser hardening steel 38ХН3МФА in various modes. The influence factors and the mechanism of hardness modification. When analyzing the results compared to micro-hardness hardened zone after complex processing. Selects the optimum mode to achieve the desired values of physical and mechanical characteristics of the surface.
Key words: mathematical planning of experiment, laser processing, the processing mode, the power density, beam speed, microhardness.
