Abstract
Bonelike apatite formed on the surface of titanium pretreated with NaOH solution after having been immersed in simulated body fluid (SBF), while no apatite formed on the surface of untreated titanium. In the present study, electrochemical impedance spectroscopy (EIS) measurement was used to investigate the nucleation and growth of apatite on chemically treated titanium immersed in the SBF solution and the difference between the behaviors of treated and untreated titanium. Appropriate equivalent circuit models were constructed to describe the nucleation and growth of apatite and the thin oxide film formed on the surface of untreated titanium. It was found that EIS is a useful method for investigating the nucleation and growth of bonelike apatite on titanium pretreated with NaOH solution.
