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 systems, methods, and devices processing feed material utilizing a microwave plasma apparatus comprising a powder ingress preventor (PIP). In some embodiments, the microwave plasma apparatus comprises a core plasma tube and a liner; and a ring structure comprising: a bearing surface, the bearing surface contacting an interior diameter of the core plasma tube; and an opening, the opening contacting an outer diameter of the liner.

Plasma apparatus and methods for processing feed material utilizing a powder ingress preventor (PIP)

Disclosed herein are systems, methods, and devices processing feed material utilizing an upstream swirl module and composite gas flows. Some embodiments are directed to a microwave plasma apparatus for processing a material, comprising: a first flow module, a second flow module, and a liner.

Some embodiments herein are directed to devices and methods for automatically starting a plasma utilizing a wand. In some embodiments, the wand may be used to start a plasma in a plasma torch such as, for example, a microwave plasma torch or an induction plasma torch, as discussed below. The wand may comprise an elongate, hollow wand member comprising a closed distal end, a proximal end, and one or more apertures extending from a hollow interior of the wand member to an exterior surface of the wand member; and an elongate wire member positioned within the hollow interior of the wand member and extending along at least a portion of a length of the wand member, wherein the wire member is configured to be placed in operable communication through the aperture with a power source, such that the power source can be activated to in turn start the plasma within the plasma torch. The plasma torches discussed herein may be used in various applications including, for example, high volume synthesis of advanced materials such as nano-materials, micro-powders, coatings, alloy compositions for additive manufacturing.

Systems, devices, and methods for starting plasma

An apparatus for providing material feedstock into a plasma of a plasma torch includes a material feeding device having an input end and an output end. The output end of the material feeding device extends at least partially around the periphery of a plasma generated near the output end of the plasma torch. The material feeding device is oriented at an angle with respect to a central axis of the plasma torch.

Method and apparatus for feeding material into a plasma

An improved driveway gutter having a flexible gutter mat bridging the trough in the gutter for improving driving over driveway gutters. The mat is made of flexible material such as heavy rubber. The mat is placed with its flat bottom bridging the gutter, and fastened down by bolts in recessed holes in the mat. Because the mat is flexible, when a car drives over the mat it is forced down to conform with the gutter, and the top of the mat smoothes out the gutter for the car. When the weight is removed the mat springs back into shape bridging the gutter, so that the passage of water is not impeded. The fastening holes are deep enough that the fasteners do not protrude above the surface of the mat when it is deformed by a tire crossing the mat.
