| Abstract Scope |
TNZ is a new class of beta-phase titanium alloys, which have a lower elastic moduli, as compared to
conventional Ti-6Al-4V (Ti64), thereby minimizing stress shielding in metallic implants. These alloys also have non-toxic constituents. Low levels of boron additions (< 0.04 wt.%) increase the mechanical strength and improve the corrosion behavior of Ti64 alloys. In this study, the corrosion behavior of Ti-28Nb-20Zr, Ti-39Nb-6Zr, Ti-6Al-4V-0.01B and Ti-6Al-4V-0.04B were compared to Ti64 in phosphate buffered saline solution (PBS) and Fusayama artificial saliva solution at 37℃. Cyclic polarization tests were used to evaluate the corrosion susceptibility of the titanium alloys to serve as implant devices. Linear polarization resistance measurements, Tafel plots, electrochemical impedance spectroscopy (EIS) measurements and scanning electrochemical microscopy (SECM) were conducted to obtain deeper insights into corrosion behavior and surface passivation. Preliminary results in PBS show that these alloys are expected to corrode at lower rates. |
