Paton Elektric Welding Institute National Academy of scinces of Ukraine popup.description1 Investigation of the peculiarities of metallurgical interaction of metal shell filled with powders of metals, alloys and refractory compounds in conductive powder wires within plasma-arc spraying, as well as formation patterns of spherical granules and powders from dispersed melt, their volume, shape, structure, composition and characteristics popup.description2  The influence of the equipment's technological parameters and design features in the process of plasma-arc spraying of conductive wires of different chemical compositions on the particle size distribution and sphericity of the obtained particles during their solidification and spheroidization in various environments was investigated. The features of the formation of the structure, chemical, and phase composition of particles, and coatings of the intermetallic type were clarified. The energy efficiency and productivity of the specified plasma-arc spraying of powder wires were investigated, and a comparative analysis of these indicators was made with other common methods of plasma spheroidization of wire materials. The effectiveness of additives of nano-sized ZrO2 and NbC powders for improving the sphericity of metal powders obtained by the plasma-arc spraying method was shown. Scientific principles were developed for the design and manufacture of industrial equipment and the practical implementation of obtaining spherical particles using plasma technologies from complex alloys and intermetallics for use in additive technologies and powder metallurgy.
