| Abstract Scope |
Ultrasonic atomization is one of the least studied and known processes used for manufacturing metallic powders. The newly developed induction and plasma-based ultrasonic systems allow to speed up the research and introduction of new materials for Additive Manufacturing. The technology involves ultrasonically agitated sonotrodes that allow the spraying of molten alloys with tailored chemical composition.
Examples of ultrasonic atomization for pulverization of multiple R&D systems from light alloys such as Mg-Li up to refractory High Entropy Alloys such as WtaVTi have been shown. The manufactured powder is characterized by high quality in terms of contamination, narrow particle size distribution which can be controlled by the frequency of ultrasonic vibrations, lack of satellites, and exceptional sphericity. Additionally, use of ultrasonic atomization for Zr-based alloys screening has been shown. |
