TC4 titanium alloy powder for 3D (Three Dimensional) printing and preparation method thereof

The invention relates to a TC4 titanium alloy powder for 3D (Three Dimensional) printing and a preparation method thereof. The method comprises the following steps: adopting an electrode induction smelting gas atomization process; crushing an alloy smelting solution into fine liquid drops under the impaction effect of high-speed inert gas flow; cooling and condensing in an atomization tower; finally, obtaining the titanium alloy powder; then proportioning powder with different granularities by applying an ultrasonic vibration and airflow classification method to prepare the TC4 titanium alloy powder applicable to different metal 3D printing technologies. Compared with the prior art, the TC4 titanium alloy powder for the 3D printing and the preparation method thereof have the advantages of simple process, high stability and controllable granularity; the prepared TC4 titanium alloy powder has the characteristics of high spherical degree, uniform granularity distribution, low oxygen content, low impurity content
