High Temperature Corrosion of Ti₃AlC₂ in Ar-1%SO₂ Atmosphere

Abstract:

The layered, machinable ternary compound, Ti3AlC2, was corrosion-tested at 800, 900, and 1000oC under an Ar-1% SO2 gas atmosphere. The scale formed consisted primarily of TiO2 and α-Al2O3. As the corrosion progressed, the scale became thicker and developed into an outer TiO2 layer and an inner (TiO2,Al2O3)-mixed layer.
