摘要

By means of the electrode induction melt inert gas atomization (EIGA) equipment designed and developed by ourselves, TC4 alloy powder were prepared. In the process of atomization, the pressure plays a decisive role in the morphology and particle size of the powder. In this paper, the effect of atomization pressure on the distribution of fluid structure was studied by computational fluid dynamics (CFD). The results show that with the increase of atomization pressure, the shape of the recirculation zone is expanded and then compressed. When the gas pressure is 2MPa, the suction pressure AP is 0.498MPa, thus forming a positive pressure zone. So it is easy to liquid droplets dripping up, resulting in clogging the nozzle, which has been confirmed in the experiment.
