Corrosion behaviour of the studied Ti20Mo alloy together with the currently used metallic biomaterials Ti6Al4V, and Ti6Al7Nb alloys was investigated for biomedical applications. All the samples were examined using electrochemical techniques: linear polarization curves and electrochemical impedance spectroscopy (EIS) in electrochemical media: Ringer’s solution with proteins at 37 oC. The passive behaviour for all the Ti samples is observed for Ringer’s solution with proteins. The Ti20Mo alloy underwent spontaneous passivation, and exhibited more positive zero current potential (EZCP), and lower corrosion current densities (jcorr) than Ti6Al4V, and Ti6Al7Nb alloys. The Ti20Mo alloy appears to posses superior corrosion resistance in Ringer’s solution with proteins than the Ti6Al4V, and Ti6Al7Nb biomaterials.
