Corrosion is a natural process that occurs when metals and other materials deteriorate and degrade due to chemical or electrochemical reactions with their surrounding environment. It is most associated with metals, but other materials like ceramics and polymers can also experience a form of corrosion.
The most well-known type of corrosion is rust, which is the corrosion of iron or steel. When metals corrode, they can lose their original properties, strength, and appearance, leading to structural weakness, aesthetic damage, and reduced functionality.
