Einfluss der Düsenkontour auf atmosphärisch DC-plasmagespritzte AL₂O₃-Schichten (Nozzle-Design Effects on the Quality of APS-Alumina Coatings)

This paper investigates the influence of nozzle design on the quality of Al₂O₃ coatings produced by atmospheric plasma spraying. It compares the thermal and deposition efficiency of different plasma guns along with the porosity and adhesion strength of the resulting coatings. The intent of the study is the application of convergent-divergent nozzles as an economic alternative to the nozzles typically used for atmospheric plasma spraying. Paper text in German.
