[Reproduction of Private Spring Preparatory School Lecture 22] Explanation of the relationship between oxides that form on metal surfaces, namely rust, and fatigue strength!

Today, let's study the relationship between rust, which is the oxide that forms on the surface of metals, and fatigue strength. The characteristics of metals as industrial materials include high mechanical strength, ductility, and excellent electrical and thermal conductivity. However, on the other hand, metals have a significant drawback: they are prone to rusting. *For detailed content of the article, please refer to the PDF.
