Abstract

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.
