Corrosion tends to concentrate at sharp corners due to several factors related to geometry and fluid dynamics. At these locations, there is often a disruption in the flow of electrolytes or corrosive agents, leading to stagnation and localized attack. This stagnation can reduce the rate of fluid movement, resulting in a lower concentration of protective films or anodic/cathodic reactions.

Additionally, sharp corners can create areas of stress concentration in the material, which can further contribute to the acceleration of corrosion processes, such as pitting or crevice corrosion. Given these conditions, sharp corners become prime sites for the initiation and development of corrosion, making them more susceptible compared to other areas like flat surfaces or rounded edges, where flow and protective mechanisms may be more conducive to overall material integrity.
