Abstract
Results of corrosion resistance tests of Ti6Al4V ELI alloy after electropolishing and anodic oxidation in new baths were presented in the paper. As a result of the electropolishing and anodic oxidation significant growth of corrosion resistance was obtained. The alloy was also crevice corrosion-proof. Chemiluminescence investigation proved low chemical activity of the passive layer and AFM test showed that the layer is uniform. The main component of the passive layer of the specimens that has the highest corrosion resistance was titanium dioxide TiO2. In the layer, lower concentration of aluminum and vanadium was observed, which is beneficial for the implants. The aluminum and vanadium occurred in oxide form.
