Atmospheric plasma-sprayed (APS) thermal barrier coating (TBC) systems have been used successfully for years in the area of novel production as well as revision and repair. The effectiveness with regard to thermal insulation and thermal insulation, which is primarily dependent on the layer thickness, layer porosity, and thermal conductivity of the system, can be significantly increased. Other application criteria such as the thermal shock behavior of the system base material, adhesive layer, and TBC top layer, etc. are reliably met at the same time. Typical TBC material systems used are zirconium oxides stabilized by means of yttrium oxide or other types of stabilization. This article describes the developments in the named areas that lead to an improvement in both the technical behavior and the commercial boundary conditions. Novel types of spray additives as well as novel and further developments in process engineering are discussed. Paper includes a German-language abstract.
