Abstract
A multi-stage gas atomization preparation method of titanium alloy spherical powder for a 3D printing technology includes the following steps: bar preparation and machining step, multi-stage gas atomization powder preparation step through vacuum induction, and powder screening step. The collision probability of the metal droplets at the gas atomization stage is reduced by controlling the gas atomization pressure and the feeding speed of the titanium alloy electrode bar in a hierarchical manner, so that the collaborative control of the particle size and the surface quality of the titanium alloy 3D printing powder in the gas atomization preparation process is realized.
