Effect of Pulsed Current Frequency and Anodisation Time on Surface Properties of Electropolished and Nonelectropolished Titanium Substrates

Figure 6

EIS spectra obtained in Nyquist format for nonelectropolished titanium surfaces after anodisation at different pulsed current frequencies in 0.9% NaCl solution. Calculated (Calc) values are represented by a solid line, which were obtained by data fitting through the equivalent circuit model of Figure 7(a).
