Pitting corrosion is a form of localized corrosion that usually occurs on metal surfaces. It's characterized by the formation of small, deep cavities, or pits, that can quickly grow in size and depth. While pitting corrosion is a common term used to describe this particular type of corrosion, there are synonyms that can be used to describe the same phenomenon. Some of these synonyms include crevice corrosion, galvanic corrosion, stress corrosion cracking, and intergranular corrosion. Each of these terms is used to describe a specific type of corrosion, but they all share similar characteristics with pitting corrosion. Understanding these synonyms can help identify and prevent different forms of corrosion.
