Galvanization is a process commonly used in industries that require corrosion protection for steel and iron components. This process involves coating the metal surface with a layer of zinc and provides excellent resistance to rust and other forms of corrosion.
The galvanization process begins with the preparation of the metal surface. It is essential to remove any dirt, grease or oxide layers that may interfere with the adhesion of the zinc coating. This is usually done by chemical cleaning or mechanical methods such as sand blasting.
After cleaning the surface, the metal is immersed in a bath of molten zinc. The zinc reacts with the iron in the metal to form zinc-iron alloy layers. These layers form a barrier that protects the underlying metal against moisture, oxygen and other corrosion agents.
