摘　　要：镁合金是最轻的工程结构材料,其溶解特性、腐蚀机理以及防护措施等方面已被广泛研究,而镁合金腐蚀测试方法和技术则是这些研究的重要基础。由于镁合金的溶解过程存在负差数效应,导致其测试技术和分析方法与其他金属存在差异。本文综述了国内外关于镁合金腐蚀测试方法与技术的研究进展,介绍了镁合金测试的通用技术与特色技术,分析了各种测试技术的适用条件和应用案例,重点对比了腐蚀速率测试方法,期望为镁合金腐蚀测试方法与技术的选择提供支撑,避免因不当测试带来的错误分析和结论。Mg-alloy is the lightest engineering metal material,and its dissolution characteristics,corrosion mechanism and protective measures have been widely studied.Corrosion test methods and techniques for Mg-alloys have been critically important to the research.Due to the negative difference effect,the testing techniques and analysis methods of Mg-alloys are different from those of other metals.This paper reviews the research progress of corrosion test methods and techniques for Mg-alloys,including the general and characteristic test technologies,analyzes the applicable conditions and application cases of various testing technologies,and focuses on the comparison of corrosion rate testing methods.It is expected that the review will provide a solid foundation for the selection of reasonable corrosion test methods and techniques in the future research for Mg-alloys,which will avoid erroneous conclusions resulting from improper testing and analysis.
