【摘要】 [目的]随着制造业向轻量化、高精度和复杂化方向发展，兼具高比强度和低密度的镁合金在航空航天、汽车、电子和机电领域的应用日益广泛。然而镁合金固有的高化学活性和较差的耐蚀性制约了其产业化应用。[方法]综述了镁合金磷磷酸盐、稀土、钛/锆、锡酸盐、强氧化剂等体系无机化学转化的研究进展。[结果]对比了不同转化膜体系的共性与差异，为镁合金化学转化的研究提出了新思路。[结论]为获得兼具高致密性、优良导电性和自修复功能的转化膜，未来研究应着力于基体动力学、优化成膜工艺参数、引入可变价态元素，并探索多层复合膜构筑，从而推动镁合金在高端制造中的应用。更多还原

【Abstract】 [Objective] With the development of manufacturing industry towards lightweight, high precision, and complex designs, magnesium alloys are increasingly applied to aerospace, automotive, electronics, and electromechanical fields due to their high specific strength and low density. [Method] The recent advancements in inorganic chemical conversion for magnesium alloys, including phosphate, rare earth, titanium/zirconium, stannate, and strong oxidizer systems were reviewed. [Result] The similarities and differences among various conversion systems were compared,providing new insights for research on chemical conversion of magnesium alloy. [Conclusion] To develop conversion coatings with high compactness, excellent conductivity, and self-healing properties, future studies should focus on substrate dynamics, optimization of film-forming parameters, incorporation of multivalent elements, and exploration of multilayered coatings, thereby promoting the application of magnesium alloys in high-end manufacturing.更多还原
