摘要
镁合金是目前实际使用的密度最小的一种金属材料,具有比强度高、导电导热性能好、切削加工性好、生物相容性良好等特点,但由于其化学稳定性差且表面氧化膜疏松多孔,耐腐蚀性能差,导致其应用受到严重限制。综述了镁合金在大气环境中的腐蚀行为,总结了其常见的表面处理技术,如化学氧化、阳极氧化、微弧氧化、有机涂层等方法的研究现状,最后对镁合金在大气环境中的腐蚀行为及表面处理技术方面的研究方向进行了展望。
Magnesium alloy is a metal material with a smallest density in practical use.It has high specific strength,good electrical and thermal conductivity,good machinability and good biocompatibility characteristics,but its application is severely limited due to its poor chemical stability,loose and porous surface oxide film and poor corrosion resistance.The corrosion behavior of magnesium alloys in atmospheric environment is reviewed,and the research status of common surface treatment techniques,such as chemical oxidation,anodic oxidation,micro-arc oxidation and organic coating,is summarized.Finally the research directions of corrosion behavior of magnesium alloys in atmospheric environment and surface treatment techniques are prospected.
