Systematic investigation of the temperature field in Atmospheric Plasma Processing (APP)

Besides chemical or mechanical surface treatments, the application of atmospheric plasma processing (APP) is a popular pre-treatment in coating and joining technology. During APP the substrate is put under a thermal cycle which is performed by a plasma torch. After the pre-treatment is completed, the subsequent coating process starts. APP leads to an ultra-finely cleaned surface, which significantly improves the layer quality after coating [1]. The pre-treatment reduces contaminations and improves the wettability as well as the adhesion of the final layer. Numerical simulations are often used to get a better understanding of the process and parametric interaction. This work gives an insight of an experimentally developed, temperature based data base to validate a numerical simulation of APP.
