摘要：
An advanced high temperature environmental barrier coating system is disclosed for protecting Si-based ceramics and SiC/SiC ceramic matrix composites (CMCs). This innovation provides a series of environmental barrier coating composition systems to achieve exceptional temperature capability, erosion and calcium-magnesium-aluminosilicate (CMAS) resistance and durability of the environmental barrier coated ceramic turbine engine hot-section components, in harsh turbine engine environments. The environmental barrier coating systems have been demonstrated for 1650° C. temperature capability and help prime-reliant designs.
