Mg-alloy is the lightest engineering metal material,and its dissolution characteristics,cor-rosion mechanism and protective measures have been widely studied.Corrosion test methods and tech-niques 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 ex-pected that the review will provide a solid foundation for the selection of reasonable corrosion test meth-ods and techniques in the future research for Mg-alloys,which will avoid erroneous conclusions resulting from improper testing and analysis.
