Corrosion resistance and biocompatibility of the Ti-25Nb-xSn alloys and commercially pure titanium (c.p. Ti) were investigated for biomedical applications. Polarization tests in Hank's solution showed a passive electrochemical behavior of the Ti-25Nb alloy after alloying Sn. The passive behaviors are observed for all Ti-25Nb-xSn alloys. XPS showed that the TiO_2 passive films strengthened by the Nb_2O_5 and SnO_2 result in improved corrosion resistance of the Ti-25Nb-xSn alloys. The biocompatibility of all specimens was evaluated by culturing MG-63 cells for 1, 4 and 7 days. MG-63 cell growth on all specimens showed good biocompatibility. The results show the excellent corrosion resistance and biocompatibility of the Ti-25Nb-xSn alloys for biomedical applications.
