Beschreibung
Zusammenfassung:	The invention provides a spherical vanadium alloy powder and a preparation method and application thereof. The preparation method comprises the steps that a vanadium alloy bar is arranged in a vacuumenvironment; inert gas is introduced into the vacuum environment for air replacement, and the oxygen content in the vacuum environment after replacement is below 5 ppm; an electric arc is utilized forenabling a liquid film out of the end face of the vanadium alloy bar; the vanadium alloy bar is rotated, and the liquid film is smashed into micro liquid drops under the centrifugal force effect; andcooling is carried out to obtain the spherical vanadium alloy powder. The spherical vanadium alloy powder can comprise powder prepared through the preparation method of the spherical vanadium alloy powder. The application can include application to the field of laser or electronic beam additional materials, and/or application to the field of laser or electronic beam cladding, such as applicationto electronic beam 3D printi
