Resum: | Glass-forming Ti-based alloys are considered as potential new materials for implant applications. Ti75-xZr10NbxSi15 alloys (free cytotoxic elements) can be produced as melt-spun ribbons with glassy matrix and embedded single β-type macrocrystals. The corrosion and passivation behavior of these alloys in their homogenized melt-spun states have been investigated in Ringer solution at 37º C in comparison to their cast multiphase crystalline counterparts and to cp-Ti and β-type Ti-40Nb. All tested materials showed very low corrosion rates as expressed in corrosion current densities i corr <50nA/cm2. Electrochemical and surface analytical studies revealed a high stability of the new alloys passive states in a wide potential range. This corresponds to low passive current densities. . . |
