摘要

Hot corrosion behaviour of Nb-16Si-24Ti-6Cr-6Al-2Hf (at.%) in the mixture of Na₂SO₄ and NaCl melts at 900°C was studied. The results show that the corrosion kinetics of the alloy fit parabolic law. The oxides consist of a loose and porous outer layer and an internal oxidation zone. Outer oxides are mainly composed of TiO₂, TiNb₂O₇, Nb₂O₅, CrNbO₄ and SiO₂ while the internal oxidation zone is composed of TiO₂. Hot corrosion mechanism of the alloy in the presence of Na₂SO₄ and NaCl deposits is discussed.
