Abstract Scope |
The development of ultra-pure spherical powder for high-performance manufacturing and advanced manufacturing applications through plasma spheroidization was successful. The feedstock of tungsten powder in three sizes - fine, medium, and coarse were processed to produce spherical powders that were near-net density with high purity. The process was able to accommodate a variety of particle sizes by tailoring plasma power, gas compositions as well as powder injection location. The optimized powder met strict purity, flowability and density requirements of aerospace, medical, defense and nuclear industries. Other refractory metal powders such as Molybdenum, Rhenium, Tantalum and Niobium were also processed in this effort using similar technique. |
