Abstract: ［Objective/Significance］ Magnesium is chemically reactive and has poor corrosion resistance，which severely restricts its application in aerospace，automotive manufacturing，electronic products，biomedical，and other fields. Among various protective measures，corrosion inhibitor technology has gradually become an important research direction in the field of magnesium alloycorrosion protection due to its advantages of economic efficiency and ease of operation.［Analysis/Discussion/Progress］ Focusing on the research progress of magnesium alloy corrosion inhibitors in recent years，this paper systematically reviews the development status of inorganic， organic，composite，and green corrosion inhibitors according to their chemical composition，summarizes the corrosion inhibition mechanisms of various inhibitors，and provides an outlook on the futuredevelopment trends of the magnesium alloy corrosion inhibitor field based on existing research results.［Conclusion/Prospect］ The future development of magnesium alloy corrosion inhibitors requires breakthroughs across multiple dimensions：building upon high corrosion inhibition efficiency，while simultaneously meeting the comprehensive requirements of environmental friendliness，strong structural designability，and low cost.
