镁锂合金耐蚀性差是制约其广泛应用的关键问题.本文在总结大量镁锂合金腐蚀行为研究的基础上,阐述镁锂合金腐蚀行为的影响因素和提高其耐蚀性的加工工艺.首先,介绍镁锂合金的腐蚀特点;然后,重点解释晶粒尺寸、晶粒取向、第二相和表面膜对腐蚀行为的影响规律,并通过合金化、塑性变形和热处理工艺改变镁锂合金腐蚀性能.进一步深入讨论镁锂合金的腐蚀机理;最后,提出针对提高镁锂合金耐蚀性应重点关注的方面.
Corrosion behavior of Mg−Li alloys: A review
It has been known that the lack of excellent corrosion resistance is the key problem restricting the wide application of Mg−Li alloys. Based on a quantity of literature about corrosion behavior of Mg−Li alloys, this review elaborates the factors affecting the corrosion behavior of Mg−Li alloys and the processing methods for improving corrosion resistance. The corrosion characteristics of Mg−Li alloys are described firstly. Then, it is explained that the grain size, orientation, second phase, and surface film strongly influence corrosion performance, which can be tailored by alloying, plastic deformation, and heat treatment. Further in-depth discussion about the corrosion mechanisms for Mg−Li alloys was also presented. Finally, important points of improving corrosion resistance are suggested.
