Abstract
The large number of parameters involved in plasma spraying leads to both a high level of effort when optimizing parameter sets for new layer materials and also to a more difficult process control for quality assurance. To reduce the influencing variables to a manageable number, this paper considers the particle properties of temperature, speed, and diameter. These particle properties are examined with the diagnostic system DPV2000 in-flight before the actual spraying process. For this purpose, the Triplex 1 with a laminar plasma flame is used as the burner. From the resulting process maps, simple conclusions can be drawn about the choice of parameters and, moreover, when comparing the same system parameters, possible deviations in the particle properties can be determined, whereby a quality control can be carried out. Paper includes a German-language abstract.
