Enhancement of titanium alloy corrosion resistance via anodic oxidation treatment

Abstract

The present work presented the electrochemical treatment of anodic oxidation of TA6V alloy and pure titanium, along with the evaluation of the passivity currents of the TA6V alloy treated under varying conditions. The test electrolyte used in the anodic oxidation was a chromic acid (CA) solution with and without the addition of hydrofluoric acid (HF). On the anodized samples, the passivity current was remarkably decreased, and the range of passive potentials was increased.
