[15C-T1-13] Experimental & Numerical Study of Gas Atomization for Improved Sphericity of Powders and Effect of Performance Parameters on Gas Atomization Process: A Review
Keywords:Additive manufacturing, Atomized Powder, Gas nozzle, Performance parameters
Additive manufacturing techniques such as 3D printing, electron beam melting (EBM), selective laser melting, and metal injection molding have become increasingly popular due to their unique benefits & high-performance manufacturing capabilities. However, these emerging processes still require well-characterized powder materials. The gas atomization technique offers a promising solution for producing metal powders suitable for these processes. Hence, the most comprehensive review presented on analysis of the gas atomization technique incorporating recent experimental and computational investigations that delve into different atomization parameters. These parameters encompass operational parameters, geometrical parameters, and physical properties of the molten metal. Such an extensive exploration aims to enhance the better understanding of the effect of these parameters on the size, shape, and morphology of the gas-atomized powder. Recent nozzle designs and their performance are also introduced.
