The Influence of Anodising Voltage on Tribocorrosion Behavior of Anodized Ti-6Al-4V Alloy

M Garsivaz, M Golozar, K Raeissi
In this study, the chemical composition, thickness and tribocorrosion behavior of oxide films prepared on Ti-6Al-4V alloy by anodising treatment in H 2 SO 4 /H 3 PO 4 electrolyte at the potentials higher than the dielectric breakdown voltage were evaluated. The thickness measurement of the oxide layers showed a linear increase of thickness by increasing the anodizing voltage. The EDS analysis of oxide films demonstrated precipitation of sulfur and phosphor elements from electrolyte into the
