The electrochemical behavior of three different near-β titanium alloys (composed by Ti, Nb and Sn) obtained by powder metallurgy for biomedical applications has been investigated. Different electrochemical and microscopy techniques were used to study the influence of the chemical composition (Sn content) and the applied potential on themicrostructure and the corrosion mechanisms of those titaniumalloys. The addition of Sn below4wt.% to the titanium powder improves the microstructural homogeneity and generates an alloy with high corrosion resistancewith
lowelasticmodulus, beingmore suitable as a biomaterial.When the Sn content is above 4%, the corrosion resistance considerably decreases by increasing the passive dissolution rate; this effect is enhanced with the applied potential.
