The stability and reliability of power supply are crucial for driving economic growth and ensuring sustainable development. Among the factors threatening engineering equipment safety, metal corrosion is particularly significant, with iron (Fe), aluminum (Al), and their alloys being the most vulnerable to degradation. This review provides a systematic overview of the corrosion mechanisms, protection strategies, and monitoring technologies for Fe and Al metals and their alloys. The discussion begins with an analysis of the primary corrosion forms affecting these materials, emphasizing the role of environmental and material-specific factors. Advances in corrosion protection methods, including surface treatments, protective coatings, and the utilization of corrosion products to enhance material durability, are examined in detail. Furthermore, the application of real-time and unmanned platform technologies for corrosion monitoring is highlighted, with a focus on their potential to improve monitoring efficiency, accuracy, and safety evaluations. These technologies provide robust data and technical support for the development of targeted corrosion-resistant solutions. This review aims to offer insights into the current challenges and future directions in the study of Fe and Al corrosion resistance, serving as a reference for both researchers and practitioners in the field of engineering.
