| Abstract Scope |
Laser-based ultrasonic atomization represents an alternative to traditional induction and plasma melting routes, particularly when avoiding crucible contamination, reaching ultra-high processing temperatures, or even intentionally evaporating material is required. This study explores the integration of AM scanning strategies into the ultrasonic atomization process. By utilizing galvo-scanner, the beam can be manipulated across the sonotrode to optimize melt pool behavior and thermal distribution. To understand the interaction between the laser beam and high-frequency vibrations, a single-track analysis was performed. Ex-situ characterization of the track morphology was used to evaluate how surface acoustic waves disrupt the molten capillary. The results map the transition from continuous track solidification to immediate droplet detachment, establishing the boundary conditions required for stable atomization and providing a framework for tailoring the process. Case studies detailing the atomization of refractory materials, complemented by powder characterization, will be presented. |
