What is corrosion and explain the mechanism of corrosion?

Corrosion is the gradual deterioration of materials, typically metals, due to chemical reactions with their environment, often involving moisture, oxygen, and other corrosive agents. The mechanism of corrosion often involves an electrochemical process where metal atoms lose electrons and form positively charged ions, leading to oxidation. This process can occur through various pathways, including uniform corrosion, pitting, and galvanic corrosion, often exacerbated by factors like acidity, temperature, and the presence of salts. Ultimately, corrosion compromises the integrity of structures and components, leading to failure if not properly managed.
