The anodic TiO₂ layers which are prepared in various anodization conditions exhibit their specific color depending on the thickness of TiO₂. In this study, the relationship between the color of TiO₂ layer, which is grown by PEO (Plasma electrolytic oxidation), and the thickness of the TiO₂ layer is investigated. To evaluate the color change of the TiO₂ layer, the value of color (dE*ab) is measured and calculated by spectrophotometer and chromameter. As a result, it is found that dE*ab values and thickness of TiO₂ layers form a linear relationship with meaningful formular. This formula can be helpful to quantify the thickness of the TiO₂ layer by the numerical dE*ab values. In this process, the spectrophotometer shows more precise results than the chromameter dose. If fluoride ions (F-) are included in the electrolyte, it will affect the dE*ab values of the TiO₂. layer. This is against the propensity, which is analyzed by XRD (X-ray diffraction) and XPS (X-ray photoelectron spectroscopy). It is important that the formular suggested in this study provides other metals which can be also anodized with the possibility of quantifying the thickness of the TiO₂ layer by the dE*ab values.
