The research status of hydrogen evolution during magnesium alloy′s corrosion process and the feature of hydrogen evolution were reviewed. In addition, we also summarized those theories for Negative Difference Effect (NDE) during magnesium corrosion and discussed the corresponding shortcomings. The effects of hydrogen on magnesium′s corrosion behavior were generalized. Moreover, the classical method to measure the hydrogen evolution were reviewed and its disadvantages were pointed out. Finally, the Scanning Electrochemical Microscopy (SECM) was introduced as a new method to detect the hydrogen, as well as our work on hydrogen evolution and spatial distribution based on SECM.
