Plasma spraying is a well established process for producing ceramic and metallic coatings for many technical applications. The quality of the coatings and the efficiency of the process depend on the powder and on the operating parameters as well as on the plasma torch properties. Whereas many efforts have been made on creating novel powders and on optimizing the operational parameters, the principle, however, of DC plasma torches has remained unchanged for many years. This was the reason for developing a novel DC plasma torch system. This paper presents the construction and operating principle of this innovative torch system. Its high performance is demonstrated in selected ceramic coatings. Paper includes a German-language abstract.
