The phenomenon of metal damage caused by chemical or electrochemical interactions with the surrounding environment is termed metal corrosion. Rusting represents the most common form of metal corrosion. Corrosion can be classified based on different criteria:
Characteristics of the corrosion process: chemical corrosion and electrochemical corrosion.
Environmental media: atmospheric corrosion and soil corrosion, among others.
Damage patterns: uniform corrosion and localized corrosion, etc.
