Abstract:
With the booming of additive manufacturing, metal powder manufacturers are facing a growing demand of gas atomized powder complying with very stringent technical specifications in terms of oxidation or particle size distribution (PSD).From a metal powder producer perspective, optimizing the PSD makes possible to be more selective in terms of targeted markets and results in a direct increase of profitability, also limiting waste and thus carbon footprint.Most of the atomization processes deal with a complex interaction between the metal and a gas jet. The literature of metal powder production stands for a narrowing of the particle size distribution with the optimization of the momentum of the gas jet. It could include the change of the flow, pressure and temperature of the inlet gas but also its composition, considering gas mixtures.This work presents results of trials conducted on an industrial gas atomization unit using nitrogen as gas stream to atomize
