Abstract
A powder treatment assembly and method for treating a feedstock powder of feedstock particles includes directing the feedstock powder into a plasma chamber within a reactor, exposing the feedstock powder to a plasma field generated by a plasma source to form a treated powder having treated particles with an increased average sphericity relative to the feedstock particles, and supplying a hot gas sheath flow downstream of the plasma chamber, the hot gas sheath flow substantially surrounding the treated powder.
