Abstract:Gas-assisted atomization is used to produce metal powders for additive manufacturing. In these systems
the primary atomization governs the powder size distribution, but it is experimentally challenging
to investigate. In this study, the primary atomization of a molten metal spray was monitored with
a calibrated high-speed camera and digital image processing. The technique enabled the generation of
spatio-temporal maps at different distances from the nozzle. Among the characteristics of the spray,
mean values a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
