Abstract

Sacrificial metallic coatings are an effective strategy for mitigating corrosion in steel operating in industrial environments. This review article focuses on examining the protection mechanism of zinc-aluminum-magnesium (Zn-Al-Mg) coatings on steel substrates. Specifically, it investigates the effects of various elements and their corrosion products on the corrosion resistance of Zn-Al-Mg coatings. Furthermore, this review summarizes the formation mechanisms of various specialized corrosion modes that occur following the corrosion of Zn-Al-Mg coatings, based on previous experimental findings. It also includes suggestions for further research areas that could contribute to the development of highly corrosion-resistant and long-lasting coatings. These suggestions are based on published laboratory and field test results available in literature.

元素和合金相对大气环境中 Zn-Al-Mg 涂层钢耐腐蚀性的影响机理：综述

人工金属涂层是减轻工业环境中钢材腐蚀的有效策略。这篇综述文章重点研究了钢基体上锌铝镁（Zn-Al-Mg）涂层的保护机制。具体来说，文章研究了各种元素及其腐蚀产物对锌铝镁（Zn-Al-Mg）涂层耐腐蚀性的影响。此外，本综述还根据以往的实验结果，总结了 Zn-Al-Mg 涂层腐蚀后各种特殊腐蚀模式的形成机制。本综述还就进一步的研究领域提出了建议，以促进高耐腐蚀性和长效涂层的开发。这些建议是根据文献中已公布的实验室和现场测试结果提出的。
