An investigation was conducted to assess the potential of water-stabilized plasma (WSP) spraying for applying protective boron carbide coatings to fusion reactor components. This paper describes how test samples were produced and how coating quality was determined. The authors sprayed boron carbide powder onto steel and stainless steel substrates using different powder feeding and spraying distances, substrate preheat temperatures, and carrier gases. They also investigated methods for optimizing the plasma jet and improving coating adhesion. The boron carbide coatings were characterized based on phase composition, porosity, oxygen content, and flexural strength. Paper includes a German-language abstract.

This paper describes the development and evaluation of multifunctional coatings for outdoor parabolic antennas. The plasma-sprayed composite coatings provide corrosion protection, reduce solar heating, and improve the absorption of EM radiation at the edges of the antenna while impeding its flow in other areas. The coatings also reduce the impact of the support structure on antenna performance. Paper includes a German-language abstract.
