Electrochemical and cellular behavior of ultrafine-grained titanium in vitro

• Equal channel angular pressing was used to produce the UFG structured titanium.
• The electrochemical behavior of Ti samples in simulated body fluid was evaluated.
• Cellular behavior of Ti samples was assessed using fibroblast cellules.
• Corrosion and biological behaviors of UFG-Ti were improved in comparison with CG-Ti.

The electrochemical and cellular behavior of commercially pure titanium (CP-Ti) with both ultrafine-grained (UFG) and coarse-grained (CG) microstructure was evaluated in this study. Equal channel angular pressing was used to produce the UFG structure titanium. Polarization and electrochemical impedance tests were carried out in a simulated body fluid (SBF) at 37 °C. Cellular behaviors of samples were assessed using fibroblast cells. Results of the investigations illustrate the improvement of both corrosion and biological behavior of UFG CP-Ti in comparison with the CG counterpart.
