Title
(EN) PLASMA ATOMIZATION METAL POWDER MANUFACTURING PROCESSES AND SYSTEM THEREFOR
Abstract
(EN)

A plasma atomization metal powder manufacturing process includes providing a heated metal source and contacting the heated metal source with the plasma of at least one plasma source under conditions effective for causing atomization of the heated metal source. The atomization may be carried out using a gas to metal ratio of less than about 20, thereby obtaining a raw metal powder having a 0-106 μm particle size distribution yield of at least 80%. The process may further include aligning the heated metal source with the plasma of at least one plasma source. An atomizing system may include an alignment system positioned upstream of the plasma source and adapted to adjust an orientation of the metal source relative to the at least one plasma source.
