Physical and chemical characterization techniques for metallic powders



John A. Slotwinski, Paul E. Stutzman, Stephanie S. Watson, Edward J. Garboczi, Max A. Peltz, Chiara F. Ferraris


Systematic studies have been done on two different powder materials used for additive manufacturing: stainless steel and cobalt-chrome. An extensive array of characterization techniques were applied to these two powders. The physical techniques included laser diffraction particle size analysis, X-ray computed tomography for size and shape analysis, and optical and scanning electron microscopy. Techniques sensitive to chemistry, including X-ray diffraction, elemental analysis using the X-rays generated during scanning electron microscopy, and X-ray photoelectron spectroscopy, were also employed. The background of these techniques will be summarized and some typical findings on virgin additive manufacturing powders will be given.
