Abstract

The Ti–20Nb–20Zr β-rich titanium alloy for medical applications obtained by electron beam casting was studied. According to electrochemical studies in simulated body fluid (Hank’s solution), it was found that the Ti–20Nb–20Zr alloy had better anti-corrosion properties (higher corrosion potential and lower corrosion current) than widely used alloys such as commercially pure Ti, Ti–6Al–4V and Ti–6Al–3Nb–2Zr alloys. The main corrosion mechanisms of the studied alloys in Hank’s solution were considered and the influence of the phase-structural state on their electrochemical behavior was assessed
