摘要: The hot corrosion behaviors of new-type Ni–Cr-based superalloys were investigated at elevated temperature. effect Nb or/and Y on resistance was by kinetics. Surface morphology the products observed SEM and phase constituents analyzed XRD. Results showed that scales alloys consisted Cr2O3, Al2O3, TiO2, NiCr2O4. NiO only detected in alloy without Y. With addition Y, notably improved. action mechanisms discussed this study.
