镁合金缓蚀剂研究进展

Research Progress of Corrosion Inhibitor for Mg-alloy

镁化学性质活泼,在水溶液环境中腐蚀速度较快,很大程度上制约了镁合金的大规模应用。缓蚀剂是目前腐蚀与防护领域应用最广泛的一种技术,具备高效、成本低等特点,可在工业应用中大幅度提高镁合金的耐蚀性能。本文依据缓蚀剂的化学组成进行分类,概述无机、有机缓蚀剂以及复配缓蚀剂的研究进展,通过总结缓蚀机理对镁合金缓蚀剂未来的研究方向提出了展望。

High chemical activity leads to rapid corrosion for Mg-alloys in aqueous solution, which restricts its wide range of applications. As one of the most widely used anti-corrosion means, corrosion inhibitor has shown high efficiency and low cost, which can greatly improve the corrosion resistance of Mgalloys in industrial applications. Based on the chemical composition of inhibitors, the research progress of inorganic, organic and compound corrosion inhibitors was reviewed in this paper. The inhibition mechanism and future research direction of corrosion inhibitors for Mg-alloys were also proposed.
