This work describes the experimental results of thermal diffusivities, thermal conductivities, and thermal resistivities of single coatings, double coatings, and sintered ceramics of 4 mol% Y2O3-stabilized ZrO2 in a temperature range from room temperature to 1000 °C. The fractured surface of the coated samples revealed a columnar microstructure. The thermal conductivities and thermal diffusivities of both EB-PVD coatings and sintered ceramics decreased with increasing temperature. The thermal diffusivities and thermal conductivities of double-layer coatings were lower than those of single-layer coatings and sintered ceramics at a given temperature.
