In this paper, a coating system for a thermal barrier, consisting of a CoNiCrAlY adhesive layer (HVOF) and a zirconium dioxide top layer (APS), is optimized with the help of particle diagnostics. The paper describes the optimization approach for a thermal barrier coating system with the aid of particle diagnostics and considering the results of the hot tests carried out within the scope of TEKAN on the DLR technology test stand P8 in Lampoldshausen. The objective is to engineer a thermal protective coating in a duplex setup for a cryogenic rocket engine and its heat flow densities of approximately 80-90 MW/meter square. Paper includes a German-language abstract.
