This paper presents basic studies on atmospheric plasma spraying using particle pyrometry and thermography. Using the example of aluminum oxide and zirconium dioxide, the influences of the particle properties and the substrate temperature on the resulting layer properties are examined. A method is presented with which the essential particle properties can be identified and the individual processes can be classified. The investigations show that the influence of the substrate temperature must not be neglected if layer properties are to be predicted as part of a quality control. Paper includes a German-language abstract.
