THE GEOMETRICAL CHARACTERISTICS OF THE HEAT AFFECTED ZONE IN THE LASER TREATMENT OF STEEL 38ХН3МФА
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.
