Crevice corrosion is a localized form of corrosion that occurs in confined spaces or crevices, such as those found between metal surfaces, under gaskets, or in joints. This type of corrosion is often exacerbated by stagnant water or moisture, which can create an environment that promotes the breakdown of protective oxide layers on metals. The process typically involves the accumulation of corrosive agents, like chlorides, within the crevice, leading to a significant difference in electrochemical potential between the crevice and the surrounding area. This can result in rapid metal deterioration, making crevice corrosion a concern in various applications, including marine environments and aerospace components.
