What is the process of slow eating away of iron metals due to attack of atmospheric moisture and oxygen called?

💡 Solution & Explanation

Rusting is a specific electrochemical corrosion process wherein iron reacts with atmospheric oxygen and moisture over an extended period to produce hydrated iron oxide. Galvanization, conversely, is a protective industrial method involving the coating of iron or steel with a thin layer of zinc to prevent such oxidative degradation. Environmental factors like salinity and humidity significantly accelerate the rate of iron corrosion. Preventing rust remains a critical engineering challenge across infrastructure and manufacturing sectors.
