Atomization of Metallic Powders
|
Gas atomization refers to the process of breakup of a liquid into fine droplets, typically smaller than 150 microns, by the impingement of high-pressure jets of gas. The raw material is melted by standard procedures( air, vacuum induction melting, arc melting, or fuel heating) then it is passed through a nozzle that controls the shape and size of the metal stream and directs it through the atomizing chamber in which the metal stream is disintegrated into fine droplets by the high velocity of the gas medium. Liquid metal droplets cool and solidify as they settle to the bottom of the atomizer collector.
Our gas atomizer exists to enable the production of small batches of metallic powders to test new compositions and for research both within and outside of The University of Alabama. We have successfully made different metal powders by gas atomization:
