Abstract: This paper examines the impact of the energy characteristics of the energy input (power density and speed of movement "laser spot" on the surface) in the laser surface treatment, and the initial state of the microstructure of steel 38ХН3МФА ГОСТ 4543-71 on the geometric dimensions of the heat-affected zone with the use of the method of mathematical planning of experiments. The role of plasma processes in the laser treatment, the effect of the initial structural state of steel on the geometric dimensions of the heat-affected zone. The quantitative characteristics of these factors and their influence on the geometrical dimensions of the heat-affected zone.
Key words: geometric characteristics of the heat affected zone, laser processing, the processing mode, the power density, the speed of movement of the beam, mathematical planning experiment.
