Spheroidization for additive manufacturing (AM)

Coarse powders can be subjected to thermal plasma in-flight treatment by injection into the discharge of an induction plasma torch and reaction chamber in order to obtain densification, purification and spheroidization, with a huge increase in powders fluidability that can be successfully used in several additive manufacturing (AM) applications. This treatment can be applied to various materials for particles in the range from tens to hundreds of microns, with particle size distribution almost unchanged, and small loss of precursor material.
