Corrosion of Titanium Alloys Anodized Using Electrochemical Techniques
The anodization of titanium has been an excellent option for protecting titanium and its alloys from corrosive environments such as acids and chloride systems, by generating a homogenous oxide layer. The objective of the current investigation was to evaluate the electrochemical corrosion behavior of...

| description | The anodization of titanium has been an excellent option for protecting titanium and its alloys from corrosive environments such as acids and chloride systems, by generating a homogenous oxide layer. The objective of the current investigation was to evaluate the electrochemical corrosion behavior of alloys Ti-6Al-2Sn-4Zr-2Mo and Ti-6Al-4V anodized in 1M H<sub>2</sub>SO<sub>4</sub> and H<sub>3</sub>PO<sub>4</sub> solutions at a current density of 2.5 × 10<sup>–3</sup> A/cm<sup>2</sup>. The anodization’s electrochemical characterization was achieved in NaCl and H<sub>2</sub>SO<sub>4</sub> at 3.5% wt. electrolytes. Scanning electron microscopy (SEM) was employed to determine the anodized thickness and morphology. Cyclic potentiodynamic polarization (CPP) and electrochemical impedance spectroscopy (EIS), based on ASTM G61-86 and G106-15 Standards, were the electrochemical techniques mainly employed. The anodized samples presented a change in E<sub>corr</sub> values and a higher passivation zone. The EIS plot showed a higher resistance for samples anodized in H<sub>3</sub>PO<sub>4</sub> and Ti-6Al-2Sn-4Zr-2Mo. |
