Abstract
There are many ways in producing metal powders. However metal (or alloy) chemical and physical properties as well as expected powder shape and distribution usually determine the powder production route. In most cases the optimal process is melt atomization, either by using high pressure gaseous or liquid media. In present work we designed confined annular nozzle to atomize aluminium melt by high pressure nitrogen gas. The nozzle was made in such a way that the atomizing gas cone angle, surrounding the sucked melt stream, was possible to vary between 0 and 60°. Gas exit velocities were varied between 0.5 and 2.5 Mach. The influence of those two varying parameters on particle size distribution was investigated in this work. The results were compared with other relevant work showing good agreement.
