This paper aims to clarify the thermal and mechanical properties of zirconium dioxide-cerium(IV) oxide-yttrium oxide and zirconium dioxide-yttrium oxide plasma sprayed coatings. such as phase transformation, bond coat oxidation, and thermal expansion mismatch. Both coatings showed a 7 to 11% porosity fraction and typical lamellar structure, which formed due to continuous wetting by liquid droplets. It is observed that the zirconium dioxide-cerium(IV) oxide-yttrium oxide coating turned out to be better than the zirconium dioxide-yttrium oxide because there was no phase change from the tetragonal to the monoclinic phase (which leads to a spatial expansion), because there was a smaller thermal expansion offset and the effect of the oxide growth stress the better thermal insulation was relatively small. Paper includes a German-language abstract.
