Abstract
An update and the latest results on molten metal atomization using a Pressure-Gas-
Atomizer will be given. This atomizer combines a swirl-pressure atomizer, to generate a liquid
hollow cone film and a gas atomizer to atomize the film and/or the fragments of the film. The paper
is focused on powder production, but this atomization system is also applicable for deposition
purposes. Different alloys (Sn, SnCu) were atomized to study the characteristics of the Pressure-
Gas-Atomizer. The powders produced were analyzed by laser diffraction and image processing.
Among other parameters, the molten metal mass flow (~140 – 200 kg/h), the gas mass flow and the
atomizer design were varied. The results include the effects of these variances on particle size and
particle shape.
