• The process of putting a protective zinc coating to iron to prevent rusting is known as galvanization. It extends the life of iron parts by establishing a membrane between the metal and the air, which prevents iron oxide from developing on the steel layer. • Galvanization also provides greater corrosion protection to parts that are exposed to air. • Galvanizing protects against rust and corrosion in several ways: 1. It acts as a barrier, preventing corrosive chemicals from reaching the iron beneath. 2. The zinc acts as a sacrificial anode, meaning that even if the coating is damaged, the exposed steel is still protected by the zinc that remains on it. 3. The zinc surface reacts with the environment to generate a dense, adhering patina that is impervious to moisture.
