METHOD OF METAL POWDERS PRODUCING Russian patent published in 2016 - IPC B22F9/06 B23K26/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metal powders production. Method comprises metal donor powder heating to its fusion temperature, formation of metal drops and their cooling under inert gas environment and powder collection. Metal donor powder sample surface is heated by laser radiation, which is moved within metal donor sample surface area with speed, sufficient for formation of melt bath on it with volume from 10^-5 to 10 mm³. Fused metal amount from melt bath is crushed and blown by compressed inert gas stream to allow metal drops free flight to their cooling below melting temperature. Powder particles are collected in powder trap volume.

EFFECT: enabling stable shape and fractional composition of powder, possibility to adjust average particles size and making powder with diameter of less than 50 mqm.
