This paper examines thermal insulation layer systems with regard to their thermal shock resistance, internal stresses, adhesive tensile strength and layer morphology. The research was conducted on a duplex coatings system consisting of zirconium dioxide/yttrium oxide ceramic coatings and CoNiCrAlY oxidizing and corrosion resisting coating. In all thermal insulation layer systems, the bonding layers were produced by vacuum plasma spraying. The thermal insulation layers were produced on the one hand by atmospheric plasma spraying and on the other hand by vacuum plasma spraying, and their properties were compared with one another. Paper includes a German-language abstract.
