Service performance of novel advanced environmental barrier coatings at ultra-high temperature of 1475 °C in steam environment
Source abstract
Abstract
A key strategy to design novel bond coating of advanced environmental barrier coatings (EBC) focuses on enhancing its service temperature. The SiO 2-HfO 2/Y 0.5Yb 1.5Si 2O 7 EBC system consists of the novel SiO 2-HfO 2 composite bond coating using electron beam-physical vapor deposition and Y 0.5Yb 1.5Si 2O 7 top coating with atmospheric plasma spraying. EBC was exposed to steam environments at ultra-high temperature of 1475 °C. Microstructure and service performance of EBC after exposure to steam environment were systematically analyzed. The results show that the novel EBC improves the service temperature of EBC and effectively protects SiC substrate, which is a promising candidate for EBC enhancing the service temperature.
