A review is provided about the current research and the relevant patents on magnesium/magnesium alloys corrosion in the industry and bioapplication. Except for reviewing the kinds of corrosion on galvanic corrosion, stress corrosion, corrosion fatigue, and biocorrosion, its corresponding mechanisms are also explained, such as the influence of metallurgical factors, environmental factors and simulated body fluid (SBF). Furthermore, the protection of magnesium/magnesium alloys corrosion is also expressed, for instance, surface treatment/modification, alloying, coating etc. In addition, due to the continuing challenges associated with the use of magnesium alloys, more considerations about future applications and research directions are given according to the properties improvement of magnesium alloys for the eco-friendly requirements.
