Abstract:

The ever-increasing interest in additive manufacturing (both binder jetting and LPBF) has led to a renewed interest in gas atomising research across the globe. As this is being done by workers with different atomising equipment, the opportunity arises to test both theoretical and empirical correlations on a variety of designs. This paper reviews some relevant literature and sets out some basic equations and the relevant parameters that should ideally Figureure in all reports on gas atomisation tests. A methodology is proposed to standardise reporting of date, e.g. mass-median, standard deviation, graphical methods and operating parameters to allow some benchmarking by gas atomiser operators and allow improvements to be clearly identified.
Remaining unanswered questions on gas atomisation will be discussed, which would surely benefit from more comprehensive publication, in particular the question of the importance of gas pressure in determining “efficiency” of atomisation, and how “efficiency” might be assessed and compared.
