FIELD: metallurgy.SUBSTANCE: invention relates to metal powders production. Proposed method comprises heating metal material to melting point thereof using laser radiation, formation of melt drops, cooling in free flight in neutral gas to temperature lower than melting point of metal material and collection of powder particles. Heating of metal material to melting point thereof is performed using laser radiation by cutting a specimen of metal material with displacement towards an untouched mass of material at a rate providing formation of melt in place of contact therewith. Formation of melt drops is performed in direction of plasma jet by means of its pressure and/or jet of compressed neutral gas. Powder particles are collected in volume of powder trap located on side of specimen of metal material, opposite to location of laser head for formation of laser radiation.EFFECT: higher efficiency of producing metal powder, as well as stability of shape and fractional composition of powder.3 cl, 2 dwg, 1 ex |
