Disclosed herein are embodiments of methods, devices, and assemblies for processing feedstock materials using microwave plasma processing. Specifically, the feedstock materials disclosed herein pertains to scrap materials, dehydrogenated or non-hydrogenated feed material, and recycled used powder. Microwave plasma processing can be used to spheroidize and remove contaminants. Advantageously, microwave plasma processed feedstock can be used in various applications such as additive manufacturing or powdered metallurgy (PM) applications that require high powder flowability.

Process for producing spheroidized powder from feedstock materials

Disclosed herein are devices, systems and methods of use of an improved liner for a plasma torch. In particular, a segmented liner for use in a plasma torch (e.g., annular torch, swirl torch) is provided. In general, the improved segmented liner has improved thermal shock resistance capabilities over conventional unitary liners.

Segmented liner and methods of use within a microwave plasma apparatus

Disclosed herein are embodiments of systems and method for processing feedstock materials using microwave plasma processing. Specifically, the feedstock materials disclosed herein pertain to metal powders. Microwave plasma processing can be used to spheroidize the metal powders and form metal nitride or metal carbide powders. The stoichiometry of the metal nitride or metal carbide powders can be controlled by changing the composition of the plasma gas and the residence time of the feedstock materials during plasma processing.

Systems and methods for synthesis of spheroidized metal powders

Disclosed herein are embodiments of methods, devices, and assemblies for processing feedstock materials using microwave plasma processing. Specifically, the feedstock materials disclosed herein pertains to unique powder feedstocks such as Tantalum, Yttrium Stabilized Zirconia, Aluminum, water atomized alloys, Rhenium, Tungsten, and Molybdenum. Microwave plasma processing can be used to spheroidize and remove contaminants. Advantageously, microwave plasma processed feedstock can be used in various applications such as additive manufacturing or powdered metallurgy (PM) applications that require high powder flowability.

Unique feedstocks for spherical powders and methods of manufacturing

Disclosed herein are embodiments of mechanically alloyed powder feedstock and methods for spheroidizing them using microwave plasma processing. The spheroidized powder can be used in metal injection molding processes, hot isostatic processing, and additive manufacturing. In some embodiments, mechanical milling, such as ball milling, can be used to prepare high entropy alloys for microwave plasma processing.
