Abstract

In this study, a biologically functional micro-arc oxidation film was prepared on the surface of TA2. An oxidized ceramic layer was formed on the surface of the material by applying different micro-arc oxidation voltages in the MAO electrolyte. The applied voltage has a significant impact on the relevant characteristics after micro-arc oxidation. As the voltage increases, the pore size and the thickness of the film layer continuously increase. When the voltage exceeds 400V, the oxygen content decreases, and the porosity also decreases accordingly. With the increase of the voltage, the diffraction peaks of the rutile phase with thermal stability in the coating gradually increase due to the rise of the surface energy density of the sample. When the voltage reaches 400V, it has a relatively high porosity, hydrophilicity, and corrosion resistance, which gradually decrease as the voltage continues to increase to 500V.

Keywords: Hydrophilicity; Microarc Oxidation; Oxidation Voltage; Roughness; Corrosion.
