Abstract: Methodologies, systems, and devices are provided for producing metal spheroidal powder products. Dehydrogenated and spheroidized particles are prepared using a process including introducing a metal hydride feed material into a plasma torch. The metal hydride feed material is melted within a plasma in order to dehydrogenate and spheroidize the materials, forming dehydrogenated and spheroidized particles. The dehydrogenated and spheroidized particles are then exposed to an inert gas and cooled in order to solidify the particles into dehydrogenated and spheroidized particles. The particles are cooled within a chamber having an inert gas.

Abstract: The present application relates to a plasma atomization process and apparatus for producing metallic powders from at least one wire/rod feedstock. In the process, an electrical arc is applied between the at least one wire/rod feedstock, and a plasma torch is employed to generate a supersonic plasma stream at an apex at which the electric arc is transferred to the at least one wire/rod to melt and atomize the at least one wire/rod feedstock to produce the metallic powders. An anti-satellite diffuser is employed to prevent recirculation of the powders in order to avoid satellite formation.

Abstract: The present disclosure related to a process and an apparatus for producing powder particles by atomization of a feed material in the form of an elongated member such as a wire, a rod or a filled tube. The feed material is introduced in a plasma torch. A forward portion of the feed material is moved from the plasma torch into an atomization nozzle of the plasma torch. A forward end of the feed material is surface melted by exposure to one or more plasma jets formed in the atomization nozzle. The one or more plasma jets being includes an annular plasma jet, a plurality of converging plasma jets. Powder particles obtained using the process and apparatus are also described.

Abstract: A method for producing a metal powder, comprising an electric explosion of a piece of a steel wire carried out inside a reactor at a pressure of a gaseous medium of 105 Pa and its forced circulation, characterized in that the method further comprises a pre-evacuation of a volume contained inside the reactor and pipes connecting it to a cyclone, whose lower part is equipped with a hopper, to a residual pressure of 10−2 Pa, then it is filled with carbon monoxide to a pressure of 105 Pa at a gas flow rate of 10 m/s at a reactor inlet, the electric explosion of the steel wire made of low-carbon steel is then carried out at a specific energy of 7-18 kj/g and a pulse duration of 1.2-2 μs, products of the electric explosion are extracted by gas flow through the cyclone into the hopper to deposit, once the hopper is filled, the process is halted, the hopper is disconnected from the cyclone, closed with a lid with an opening, and kept in this state for at least 48 hours, the resulting powder is then removed and placed into a container for storage.

Abstract: In the porous substrate loaded with porous nano-particles structure and one-step micro-plasma production method thereof, since the micro-plasma system enhances the electron density and promotes reaction speed in the reaction without generating thermal effect, the method may be performed at an atmosphere environment. The nano-particles also can be quickly obtained by aforementioned micro-plasma system. The electromagnetic field generated by the micro-plasma can drive the nano-particles to be loaded onto the porous substrate in a one step, rapid and low cost process to improve the conventional techniques which require a relatively long procedure time and a complicated process.
