What is Characterization and properties of the MgF2/ZrO2 composite coatings on magnesium prepared by micro-arc oxidation about?

Through micro-arc oxidation, the MgF 2 /ZrO 2 composite coatings were prepared on magnesium at the different applied voltages (in the range of 400-550 V) in a zirconate electrolytic solution. The morphologies, phase components, microhardness, bond strengths, and corrosion resistances of the composite coatings were investigated. The effect of the applied voltages on the characteristics and properties of the composite coatings and the basic formation mechanism of the coatings were also discussed. The results indicate that the composite coatings are relatively dense and uniform in thickness, and predominantly composed of MgF 2 , tetragonal ZrO 2 (t-ZrO 2 ) and monoclinic ZrO 2 (m-ZrO 2 ). The composite coatings exhibit a gradient distribution in phase component from the surface to the inner part. It is found that the applied voltage plays an important role in the characteristics and properties of the composite coatings. With the increase of the applied voltage, the thickness and the t-ZrO 2 content of the composite coatings increase, while the m-ZrO 2 content decreases and no significant variation is observed in the MgF 2 content. Moreover, the surface microhardness and bond strength
