| 目的 总结和讨论超疏水表面提高镁合金耐蚀性能的制备方法。方法 镁及镁合金因其标准电极电位低，化学活性很高，在其表面制备超疏水表面有两种途径：一是利用其高活性直接在表面制备超疏水表面；二是先构建中间过渡保护层再在镁合金上制备超疏水表面。采用电化学测试方法研究了超疏水表面的抗腐蚀行为。结果 总结了在镁合金上制备抗腐蚀性超疏水表面的最新进展，提出了超疏水表面提高镁合金耐蚀性能的机理。结论 镁合金上制备超疏水表面的方法较多，但是能进行大规模生产的较少，且制备的超疏水表面耐久性、机械稳定性较差。 |

| Objective To summarize and discuss the methods for preparing superhydrophobic surfaces on magnesium alloys to enhance their corrosion resistance. Methods For the ultra high standard potential, the Mg and magnesium alloys have a relatively high chemical activity. Thus, there are mainly two kinds of methods to prepare superhydrophobic surfaces on magnesium alloy: 1. directly prepare a superhydrophobic surface using the high chemical activity of magnesium alloy; 2. prepare a transition layer on magnesium alloy firstly and then fabricate the superhydrophobic surface. On the other hand, the corrosion behaviors of magnesium alloys with superhydrophobic surfaces were investigated by the electrochemical methods. Results The research progress of fabricating superhydrophobic surfaces with anti-corrosion function on magnesium alloys was summarized and the action mechanism of superhydrophobic surfaces in improving the corrosion resistance was discussed in this paper. Conclusion Though there were a lot of methods for preparing superhydrophobic surfaces on magnesium alloys, most of them cannot be used for the larger-scale production, and the as-prepared superhydrophobic surfaces were lack of durability and mechanical stability. |
