英文摘要	The thermal insulation performance of yttria-stabilized zirconia (YSZ) and YSZ-Al2O3coatings deposited by atmospheric plasma spraying was evaluated using a thermal shock simulator, revealing the superiority of YSZ-Al2O3coatings due to their lower thermal conductivity. Furthermore, YSZ-Al2O3coatings were more thermally stable than YSZ ones, as determined by scanning electron microscopy, electron backscatter diffraction, and energy-dispersive X-ray spectroscopy analyses. Detailed investigations revealed that heating induces partial removal of Y from ZrO2, weakening its stabilization and thus leading to a martensitic phase transformation of metastable tetragonal zirconia (t′-ZrO2) into monoclinic zirconia (m-ZrO2). Conversely, in YSZ-Al2O3coatings, Al diffused into t′-ZrO2to further stabilize it by forming an YSZ-Al2O3solid solution, thus slowing down the above phase transformation. © 2017 Elsevier Ltd and Techna Group S.r.l.
