  • Plasma spray nozzle with internal injection
    Patent number: 9309587
    Abstract: A plasma spray nozzle is provided. Owing to their high degree of wear, previous plasma spray nozzles were not suitable for the coating of components for which long coating times were necessary. The coating times may be reduced considerably by the triple injection of powder into the inner channel through the plasma spray nozzle.
    Type: Grant
    Filed: August 7, 2013
    Date of Patent: April 12, 2016
    Assignee: SIEMENS AKTIENGESELLSCHAFT
    Inventors: Mario Felkel, Heiko Gruner, Francis Ladru
  • CONTROLLED THERMAL COATING
    Publication number: 20150361542
    Abstract: The combined measurement of the particle velocity, temperature, intensity, and burner voltage and control thereof in a tolerance range makes it possible to keep the layer structure, the layer thickness and the layer weight constant in spite of wear-induced variations in the coating process.

  • CONTROLLED THERMAL COATING
    Publication number: 20150361541
    Abstract: The combined measurement of particle speed, particle temperature, particle intensity, burner current and the control thereof within a tolerance range allow the coating structure, coating thickness and the coating weight to be maintained despite wear-associated fluctuations in the coating process.

  • Spray nozzle and method for atmospheric spraying, device for coating, and coated component
    Publication number: 20120301624
    Abstract: A spray nozzle for atmospheric plasma spraying is provided. The nozzle includes an attachment at an axial end of the spray nozzle from which a protective gas may be discharged in the outflow direction. By means of a plasma spray nozzle that enables atmospheric plasma spraying using protective gas, it is also possible to deposit oxidation-sensitive metal coatings in atmosphere.
