摘      要：Scandia,yttria-stabilized zirconia (Sc2O3-Y2O3-ZrO2) powder for plasma spraying was synthesized by chemical co-precipitation *** morphology and phase stability of plasma sprayed 6.8mol%Sc2O3-1.2mol%Y2O3-ZrO2 thermal barrier coatings (TBCs) were *** of the coatings were heated at 1400℃ for 500 hours and then examined by X-ray *** was found that the Sc2O3-Y2O3-ZrO2 coatings showed excellent phase stability to retain single tetragonal t phase structure and did not undergo a tetragonal-to-monoclinic phase transition upon cooling.
