the technological and structural properties of spherical granules and the peculiarities of their production processes using industrial technologies of gas atomization, plasma rotating electrode process and plasma-arc atomization of neutral and current-carrying wires and rods are considered. It was found that among the considered methods of obtaining spherical granules, the most promising in terms of productivity, energy efficiency and simplicity of the equipment used is the method of plasma-arc atomization, which, due to the presence of a large number of technological and structural parameters of the process, allows adjusting the particles size distribution and technological properties of the granules in a wide range. experimental studies have shown that the particles size distribution, shape factor and technological properties of granules from titanium alloys and stainless steel obtained by plasma-arc atomization of current-carrying wire materials at the e.O. paton electric Welding Institute of the nas of ukraine, together with llc r&D plaZer center, are at the level of the best foreign analogues. a promising direction of increasing the energy efficiency and productivity of the process of obtaining spherical granules for additive manufacturing and granule metallurgy using the technology of plasma-arc atomization of current-carrying rods with a diameter of more than 50 mm at reverse polarity by plasma trons with a hollow copper anode is proposed.
