Corrosion and Its Prevention

Subject: Chemistry

Book: General Chemistry

Corrosion is the degradation of metals through chemical or electrochemical reactions with the environment, such as rusting of iron (Fe → Fe²⁺ + 2e–). Prevention methods include coatings (paint, galvanization), cathodic protection (sacrificial anodes), and alloying (stainless steel). Understanding electrochemical mechanisms and environmental factors (pH, temperature, electrolytes) helps in designing long-lasting materials and infrastructures.
