Abstract

The 6061 aluminum alloy ingots were gas atomized using a small-scale close-coupled atomization system. The process parameters such as gas pressure, melt rate and top pressure were varied accordingly in order to obtain the mean particle diameter (d50) of the raw powder of about 20μm. In general, it was observed that increasing the atomization gas pressure increased the amount of fine powder. At constant atomizing gas pressure and melt rate, increasing top pressure decreased slightly the amount of fine powder. The powder mean particle size (d50) of 21.6μm. This powder was produced at the gas pressure of 60 bar, melt temperature of 1200°C and gas to melt ratio of 5.46. For this type of close-coupled atomization system, it is concluded that it is not possible to obtain 100% powder with mean particle diameter (d50) of less than 20μm by varying the above process parameters.
