Abstract
- This work studied the corrosion behaviour of Ti-12Mo-6Zr-2Fe alloy with different surface conditions: untreated and chemically treated (CST), anodised nanotubes (Nt) and nanopores (NP). These samples were immersed in simulated body fluid (SBF) for 1, 7, and 14 days. Samples with Nt and NP displayed higher corrosion resistance and lower passivation current (ipass) than untreated and CST samples after 14 days resting in SBF. Furthermore, traditional equivalent circuits and a new two-channel transmission line model were employed to efficiently simulate the electrochemical impedance spectroscopy (EIS) data of the different surface conditions.
