Abstract

Discusses the process of obtaining spherical granules of a metal composite material based on molybdenum with an initial fraction of 40‒63 microns. The results obtained during the research showed the fundamental possibility of spheroidization of granules of high-temperature metal composite materials based on refractory metals reinforced with particles of ceramic compounds. However, the need for a more thorough study and selection of spheroidization modes to minimize the formation of satellites on granules during processing in an electric arc discharge plasma is revealed.
