Finite Element Method for Modelling and Mechanistic Studies of Corrosion Under Thin Electrolytes

Corrosion, particularly under thin electrolytes, poses a significant challenge across various industries, leading to substantial economic losses and safety hazards. This chapter discusses the mechanisms and impact of corrosion when metal surfaces are exposed to thin layers of electrolytes. Influencing factors like temperature, humidity, and contaminants exacerbate this process, resulting in structural degradation through the formation of pits and cracks. To mitigate such corrosion, protective coatings and regular maintenance are essential, but computational modelling, especially using the Finite Element Method (FEM), offers a powerful tool for predicting and managing corrosion. This chapter highlights the application of FEM in simulating corrosion under thin electrolyte films, emphasising its ability to handle complex, dynamic environments. Through FEM, researchers can better understand localised corrosion processes and evaluate mitigation strategies, enhancing the overall integrity and longevity of materials exposed to corrosive conditions.
