Corrosion is a pervasive phenomenon affecting materials across a multitude of scales, from the atomic to the macroscopic. This review paper presents a comprehensive examination of the methodologies employed in the analysis of magnesium corrosion, including electrochemical, non-electrochemical and analytical approaches, emphasizing the need for a diverse array of analytical tools to understand the complex interplay between corrosion, microstructure, and the dissolution mechanisms of magnesium alloys. The research showcases the utility of specific tools like SEM/EDS and SKPFM for targeted site analysis, while XPS and FTIR provide a broader perspective on specimen surfaces. The paper also discusses the value of in-situ analysis techniques, which allow for the real-time observation of corrosion processes, offering a dynamic view of the emergence and evolution of corrosion products. These in-situ methods stand in contrast to ex-situ analyses, which only permit post-experimental evaluation. By highlighting the capabilities of various analytical tools, from those that reveal surface layer details to those that probe deeper structures, and from those that detect primary elements to those that trace minute quantities of impurities, this study underscores the intricate nature of corrosion and the critical role of advanced analytical techniques in fostering a deeper understanding of material degradation. The findings advocate for the increased application of in-situ analysis in magnesium corrosion research, as it provides a more immediate and accurate depiction of corrosion dynamics, potentially leading to more effective corrosion prevention and control strategies.

研究镁及其合金腐蚀的电化学、非电化学和分析方法概述


腐蚀是一种普遍现象，影响着从原子到宏观的多种尺度的材料。本综述论文全面研究了镁腐蚀分析中采用的方法，包括电化学、非电化学和分析方法，强调需要各种分析工具来了解镁合金的腐蚀、微观结构和溶解机制之间的复杂相互作用。该研究展示了 SEM/EDS 和 SKPFM 等特定工具在目标位点分析中的实用性，而 XPS 和 FTIR 则提供了对样品表面的更广阔的视角。本文还讨论了原位分析技术的价值，该技术允许实时观察腐蚀过程，提供腐蚀产物出现和演变的动态视图。这些原位方法与非原位分析形成鲜明对比，后者只允许进行实验后评估。通过强调各种分析工具的功能，从揭示表面层细节的工具到探测更深结构的工具，从检测初级元素的工具到追踪微量杂质的工具，本研究强调了腐蚀的复杂性以及先进分析技术在促进对材料降解的更深入理解方面的关键作用。这些发现主张在镁腐蚀研究中增加原位分析的应用，因为它提供了更直接、更准确的腐蚀动力学描述，从而有可能带来更有效的腐蚀预防和控制策略。
