Properties and Performance of High-Purity Thermal Barrier Coatings
It was found that the content of impurity oxides in 7YSZ, such as SiO2 and Al2O3, has a significant effect on coating sintering resistance and phase stability of 7YSZ thermal barrier coatings (TBCs). The reduction of impurity content will significantly improve sintering resistance and phase stability of 7YSZ TBCs and thus allow the 7YSZ TBCs to be used at higher temperatures.

Abstract

It was found that the content of impurity oxides in 7YSZ, such as SiO2 and Al2O3, has a significant effect on coating sintering resistance and phase stability of 7YSZ thermal barrier coatings (TBCs). The reduction of impurity content will significantly improve sintering resistance and phase stability of 7YSZ TBCs and thus allow the 7YSZ TBCs to be used at higher temperatures.
