Size distribution of spray atomised aluminium alloy powders produced during linear atomization

In the present study, the influence of operating variables, such as atomising gas pressure and linear gas atomiser slit width, on the mass median diameter were investigated for linear spray atomization and deposition of aluminium alloy (Al-1.2Mn-0.6Si-0.7Fe00.15Cu, wt.%). In addition, the influence of atomising gas pressure on the averaged liquid mass flowrate was studied. The results indicate that the averaged liquid mass flowrate increases linearly with the atomising gas pressure differential over the range 260–380 kPa, suggesting that an aspiration effect is present.
