摘要： The present disclosure relates 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, or a combination of an annular plasma jet with a plurality of converging plasma jets. Powder particles obtained using the process and apparatus are also described.

摘要： 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.

摘要： A method for coating a surface with a coating jet containing coating particles includes forming the coating jet from at least two partial jets. The method also includes forming one of the exit channels as a spray channel for a first gas stream containing the coating particles. The method also includes forming the other of the exit channels as a control channel. In case of a deviation of the ascertained spray angle (α) from the predetermined target spray angle, the method also includes increasing the volume flow of a first partial jet of the at least two partial jets, and decreasing the volume flow of a second partial jet of the at least two partial jets.

摘要： A plasma spraying apparatus includes a cathode, a first gas nozzle surrounding a head of the cathode therewith to form a first gas path outside of the cathode, and a second gas nozzle surrounding the first gas nozzle therewith to form a second gas path outside of the first gas nozzle. The second gas nozzle is formed with a wire path through which a wire is inserted such that a distal end of the wire is disposed in front of a nozzle opening of the second gas nozzle. The wire path has a substantially rectangular cross section having a longer side extending in a direction in which a plasma flame extends, the wire path causing the wire to bend within an elastic limit of the wire.
