Abstract

Corrosion behaviour of the studied TiTa alloys together with the currently used metallic biomaterials commercial pure titanium (Cp-Ti) was investigated for dental applications. All the samples were examined using electrochemical techniques: open circuit potential, potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) in two electrochemical media: artificial saliva and in commercial mouthwash solution with 500 ppm F- (Oral B® , Gillette) at 25o C. The passive behaviour for all the Ti samples is observed for artificial saliva and for commercial mouthwash solution. The TiTa alloys appear to posse’s superior corrosion resistance than the Cp-Ti in both electrochemical media..
