METHOD FOR RAPID CHARACTERIZATION OF METALLIC POWDERS

Abstract: a method for characterization of metallic powder including presenting a metallic powder sample to a laser and detector system, wherein the metallic powder sample passes through the laser and detector system via a sample introducer; applying a pulsed laser beam to a first location in the metallic powder sample to provide a first micro-plasma at the first location in the metallic powder sample when the pulsed laser beam terminates, the micro-plasma cools to provide spectral emissions at the first location; collecting the spectral emissions at the first location in the metallic powder sample with a detector; analyzing the spectral emissions at the first location to provide a spectral analysis dataset; and identifying inclusions at the first location in the metallic powder sample.
