Abstract

This work investigates the hot corrosion behaviour of Ti-48Al-2Nb-0.3Si and Ti-48Al-2Nb-0.3Si-1Sn alloys under 25 wt.% NaCl and 75 wt.% Na₂SO₄ molten salt mixture at 900 °C. The alloys were developed through vacuum arc melting and casting. The corrosion kinetics of the alloys were measured by mass change per unit surface area. The results revealed that both alloys experienced hot corrosion attacks; however, Ti-48Al-2Nb-0.3Si-1Sn alloy demonstrated superior corrosion resistance and retained good mechanical properties compared to the Ti-48Al-2Nb-0.3Si.
