FIELD: technological processes.
SUBSTANCE: group of inventions refers to the preparation of a powder that can be used in additive technologies. Apparatus for producing powder particles comprises a plasmatron configured to supply to the plasma a starting material in the form of an elongate element, a spray unit with nozzles for supplying the atomizing gas and a chamber for collecting powder particles. Plasmatron is equipped with a nozzle with a supersonic part, made with the possibility of feeding the starting material at an angle of 10–90° to the axis of the plasmatron with simultaneous rotation. Spray unit is installed after the nozzle with a supersonic part and contains from 2 to 16 nozzles, the axes of which do not intersect the axis of the plasmatron and do not intersect with each other. Method for producing powder particles in the apparatus is also provided.
EFFECT: improvement in the quality of the powder from the material with a high melting point is provided.
