| Summary: | Titanium and its alloys are employed as medical materials because of their low Young's modulus, excellent biocompatibility, and superior corrosion resistance. This work aimed to characterize the electrochemical behavior of titanium Ti-CP2 and alloys Ti-6Al-2Sn-4Zr-2Mo, and Ti-6Al-4V. Ti and Ti-alloys were exposed to Ringer ́ssolution at room temperature. The electrochemical characterization was made by cyclic potentiodynamic polarization (CPP) and electrochemical noise technique (EN). Two different methods filtered EN signal, the polynomial method and the potential spectral density (PSD). Also, the Wavelets method, where energy dispersion plots were obtained. Results indicated thatTi-6Al-2Sn-4Zr-2Mo presented less dissolution when exposed in Ringer analysis by ψ0. The wavelet method showed a diffusion process occurring on the surface. |
