| Abstract Scope |
Typical corrosion tests of titanium for biomedical applications are usually performed in solutions such as physiological saline or PBS (phosphate-buffered saline). Nevertheless, implants in the human body are exposed to the range of other molecules including proteins (such as albumin) and ROS (reactive oxygen species, such as hydrogen peroxide). The latest investigations (related to commercially used Ti6Al4V) indicate that the influence of proteins and ROS should be investigated in combination taking into account the unfavourable synergistic effect of these two factors. In this study the effect of simultaneous presence of proteins and ROS on the corrosion resistance has been investigated for modern Ti-based materials with lack of potentially harmful alloying elements (such as bulk nanocrystalline alpha Ti or metastable beta Ti alloy). Corrosion resistance was analysed based on the results of electrochemical tests (EIS, potentiostatic polarization) combined with surface analysis (AFM, XPS).
