FIELD: metallurgy.
SUBSTANCE: method of obtaining ultradisperse powders of alloys with particles sizes of 5-200 nm and specific surface area of 80-170 m2/g includes delivery of powder of initial mixture of primary and secondary metals with particles average size of 100-150 mcm by flow of inert plasma-supporting gas to reactor of gas-discharge plasma, evaporation of initial mixture of primary and secondary metals, cooling of thermal decomposition products by cooling inert gas and condensation of obtained ultradisperse powders of alloys in water-cooling inlet chamber. During cooling of thermal decomposition products they are mixed in flame cooling zone by electromagnetic field generated by electromagnetic mixer, located from outside of reactor cooling zone.
EFFECT: obtaining ultradisperse nanosized powders of alloys with uniform distribution of components.
