Abstract The sulphation and oxidation corrosion resista nce of Ni3Al-based intermetallics has been investigated in this paper.In burning environment of inferior quality coal,Ni3Al-based alloy provided excellent prot ection against sulphation corrosion.Its properties of sulphation resistance is o ver 3.6 times that of 2520 heat resistant alloy,this is excellent commercial mat erial of sulphation corrosion resistance at high temperature.
