Abstract:
In this work, we have investigated the influence of the presence of satellites on the flowability properties of a TA6V powder. Thermal plasma treatments have been performed to spheroidize the powder at various feed rates (2 to 8 kg|h) under Ar|He atmosphere. The physical and chemical properties of the initial and treated powders have been characterized: morphology, particle size distribution, flow rate, apparent and tap densities, interstitial contents (oxygen, nitrogen and hydrogen). The results have shown that the best powder produced by plasma treatment was spherical, satellites-free and without noticeable effect on the particle size distribution. The Ar|He atmosphere leads to very low interstitial contamination. In addition, an improvement in flow rate of 30% was observed as well as an increase in apparent and tap densities of 20% and 8% respectively.
