Abstract

To date, Mg-Li alloys still face significant challenges in practical engineering applications, with insufficient corrosion resistance persisting as a major issue and a critical limitation. Micro-arc oxidation has shown remarkable effectiveness in boosting the corrosion resistance, wear resistance, and overall functionality of the Mg-Li alloy. The combination of MAO with other surface treatment methods to address the porous nature of the coating can substantially improve its corrosion resistance, wear resistance, and biocompatibility. Such progress is expected to facilitate the widespread adoption of Mg-Li alloys in sectors such as biomedicine, aerospace, automotive manufacturing, and digital technologies. This paper, based on the latest research achievements in MAO of Mg-Li alloys, summarizes the critical factors impacting MAO coating performance, highlights recent progress in post-treatment methods for fabricating composite coatings, reviews the functional properties of MAO coatings for wide-ranging applications, and provides an outlook on future research directions.

镁锂合金微弧氧化研究进展

迄今为止，Mg-Li合金在实际工程应用中仍然面临着重大挑战，耐腐蚀性不足一直是主要问题和关键限制。微弧氧化在提高Mg-Li合金的耐腐蚀性、耐磨性和整体功能方面显示出显著的效果。将MAO与其他表面处理方法相结合，解决涂层的多孔性，可以大大提高其耐腐蚀性、耐磨性和生物相容性。这一进展有望促进Mg-Li合金在生物医药、航空航天、汽车制造和数字技术等领域的广泛采用。本文基于Mg-Li合金MAO的最新研究成果，总结了影响MAO涂层性能的关键因素，重点介绍了制备复合涂层后处理方法的最新进展，综述了具有广泛应用前景的MAO涂层的功能特性，并展望了未来的研究方向。

期刊介绍： The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results. Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
