摘要

AZ31 镁合金通过微弧氧化后表面具有很高的绝缘性，对此，通过在环氧树脂中加入镍粉制备出导电涂层，对微弧氧化后的镁合金表面进行导电改性。通过场发射扫描电镜(SEM)、X 射线衍射仪(XRD)、导电测试、摩擦磨损试验、电化学测试等分析测试研究了不同镍粉含量的导电涂层的微观形貌、物相、导电性、耐磨性能及耐蚀性等。结果表明，随着镍粉含量的增加，电阻率最低可至0.02 Ω·cm。当镍粉含量为50%(质量分数)时，膜层拥有导电性的同时也有较好的耐磨性能及耐蚀性能。

Abstract

The surface of AZ31 magnesium alloy has high insulation after micro-arc oxidation treatment.For this，a conductive coating was prepared by adding nickel powder into epoxy resin to modify the surface conductivity of magnesium alloy after micro-arc oxidation.Field emission scanning electron microscopy (SEM)，X-ray diffractometer (XRD)，conductivity test，friction and wear test，electrochemical test and other analytical tests were utilized to study the micromorphology，phase，conductivity，friction properties and corrosion resistance of conductive coatings with different nickel powder content.Results showed that with the increase of nickel powder content，the resistivity could be as low as 0.02 Ω·cm.When the nickel powder content was 50%(mass fraction)，the as-modified coating not only had electrical conductivity，but also had good wear resistance and corrosion resistance.

Key words： AZ31 magnesium alloy; micro-arc oxidation; conductive modification; electrochemical corrosion
