Abstract
GdPO4 is a promising thermal barrier coating (TBC) candidate owing to its excellent resistance to calcium-magnesium-alumina-silicate (CMAS) and molten salt corrosion. In this study, the corrosion behavior of GdPO4 in CMAS + molten salt (CN) was investigated and compared with that in CMAS. At 1200 and 1250 °C, interface reaction layers rapidly formed on both the CN and CMAS attacked GdPO4 pellets, and many crystalline products were generated in the melts. This effectively increased the melt viscosity and suppressed its penetration. As compared to CMAS, CN was more aggressive to GdPO4 at 1200 °C but less at 1250 °C.
