  • Patent number: 9987703
    Abstract: The plasma spraying apparatus includes a cathode, a first gas nozzle defining a first gas path between the cathode and itself, a second gas nozzle defining a second gas path between the first gas nozzle and itself, and a third gas nozzle disposed between the first and second gas nozzles to define a third gas path between the first and second gas paths. A wire is disposed at a distal end thereof in front of a nozzle opening of the second gas nozzle. A first gas sprayed through the first gas nozzle is turned into plasma flame, which melts the wire into droplets, and the droplets are sprayed onto a target by a second gas sprayed through the second gas nozzle. The third gas absorbs heat from the plasma flame to thereby turn into a high-temperature gas flow externally of the plasma flame.

  • Patent number: 9888557
    Abstract: 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.
