Abstract (en)
[origin: US5406046A] The plasma spray apparatus for spraying powdery material, particularly for the coating of the surface of a work piece, comprises an indirect plasmatron adapted to create an elongated plasma torch, having a central longitudinal axis and structure for feeding the powdery material into the plasma torch. The plasmatron comprises a cathode assembly having at least three cathode members evenly distributed along a circle around the central longitudinal axis of the plasmatron, an annular anode member located distantly from the cathode member and a plasma channel extending from the cathode assembly to the anode member. The plasma channel is delimited by the annular anode member as well as by a plurality of annular neutrode members which are electrically insulated from each other, and the structure for feeding the powdery material into the plasma torch are located close to the anode member.
