FIELD: powder metallurgy.
SUBSTANCE: invention can be used to produce a powder from a biomedical high-entropy alloy with chemical elements harmless to the human body for subsequent process of selective laser melting and production of medical implants. Method involves high-frequency ultrasonic atomisation of alloy Ti30Zr38Nb20Ta8Sn4 in argon medium with oxygen content in chamber below 100 ppm and current 140–180 A.
EFFECT: obtaining spherical particles with average size of 53 mcm and uniform distribution of chemical composition.
