Surface Modification on Ti-6Al-4V Alloy During Corrosion in a High Temperature Ionic Liquid

Abstract:

Corrosion behavior of Ti-6Al-4V alloy was investigated by anodic polarization curves in LiF-NaF-KF molten salts mixture at 823K. The surface alloy (native composition and its modification and corrosion resistance after 4 hours immersion) was studied by XRD, SEM and XPS. XPS analysis shows TiO2 with small amount of V2O5, Al2O3 and TiF4, while in the electrolyte it was showed the presence of V in a very low concentration. AFM demonstrates that formation of a rough and non-protective oxide layer should be responsible for the weak protective properties of the alloy. The degradation mechanism of the alloy during corrosion is based on the formation of TiF4 and of the passing of vanadium in the molten electrolyte.
