Crevice corrosion is a localized form of corrosion that occurs in the stagnant microenvironments created in crevices or tight spaces. It is typically found in areas where two materials are in contact, such as under gaskets, washers, or any part where there is a gap that can trap corrosive agents, such as water or ionic solutions. The primary mechanism behind crevice corrosion involves the differential concentration of ions within the crevice compared to the external environment.
