Definitions

  • the frame element has an inner periphery, the cross section of which corresponds to the geometry of the cross section of the inner periphery of the end piece.
  • the cross section should present rotational sy ⁇ unetry.
  • two or more powder injection ports for directing a powder towards the flame are distributed around the inner periphery of the frame element.
  • an improved and more even powder distribution within the plasma jet is achieved. Since the injected powder is distributed via a number of nozzles, a larger amount of powder per time unit can be injected into the plasma without the same problem with instability that would occur if only one nozzle or port was used.
  • each powder injection port comprises a nozzle that is inserted in a radial hole or opening through the frame element, and at least one or more of the open through holes are adapted for accommodation of such a nozzle therein.
  • the frame element is equipped with a plurality of radial through holes, extending from the outside to the inside of the frame element and permitting any medium such as air to pass through them. At least some of the holes are adapted to accommodate a nozzle or the like therein. For example some holes might be provided with a thread for engagement with a nozzle, resulting in a more versatile device.
  • FIG. 3 and 4 show a first embodiment of the thermal spraying device according to the invention.
  • a flame, or plasma jet is generated by the same means as described in figs. 1 and 2.
  • a frame element 6 formed by two discrete ring parts 7,8 covers approximately 180° of a circumference around the flame. In other words, it covers 50% of the circumference that a corresponding continuous ring would have covered.
  • each ring part 7,8 defines a sector that covers at least 90° of said circumference.
  • the ring 6 has a circular inner periphery with a diameter D which is approximately equal to the inner diameter d of the end peace 1. More precisely, as in this case, the inner diameter D corresponds to the outer diameter d of the end piece 1 plus the thickness of the wall of the end piece 1.
  • a particular advantage of the invention is that a frame element 6 as described above could be used to replace the single shoulder and nozzle arrangement of prior art on widely used plasma jet guns available on the market today, such as the F4 gun, without extensive work, resulting in improved powder yield, plasma jet efficiency and stability, and less risk of powder port clogging.
