Figure 6From: Study on cerium-doped nano-TiO2 coatings for corrosion protection of 316 L stainless steelFitting curves for the impedance spectra. (a) bare 316 L and (b) 2.2% Ce-TiO2 coating. Symbols are corresponding to the experimental data and full lines are for theoretical curves. Inset in panel (a) and (b) are the corresponding equivalent circuits used for numerical fitting of the EIS dataBack to article page
