| 英文摘要 | The poor corrosion resistance of magnesium (Mg) and its alloys limits their application in various fields. Micro arc oxidation (MAO) coatings can improve the corrosion resistance, but the pore defects and low surface hardness make them susceptible to wear and accelerated corrosion during usage. In this study, a ZrO2 nanoparticles doped-MAO coating is prepared on the ZK61 Mg alloy by utilizing an MgF2 passivation layer to prevent ablation. The ZrO2 nanoparticles re-melt and precipitate due to local discharging, which produces evenly dispersed nanocrystals in the MAO coating. As a result, the hardness of the MAO coating with the appropriate ZrO2 concentration increases by over 10 times, while the wear rate decreases and corrosion resistance increases. With increasing ZrO2 concentrations, the corrosion potentials increase from -1.528 V of the bare ZK61 Mg alloy to -1.184 V, the corrosion current density decreases from 1.065 x 10-4 A cm-2 to 3.960 x 10-8 A cm-2 , and the charge transfer resistance increases from 3.41 x 102 Q cm2 to 6.782 x 105 5 cm2 . Immersion tests conducted in a salt solution for 28 d reveal minimal corrosion in contrast to severe corrosion on the untreated ZK61 Mg alloy. ZrO2 nanoparticles improve the corrosion resistance of MAO coatings by sealing pores and secondary strengthening of the corrosion product layer.
