What Is Galvanization?
Galvanization is a technique of plating zinc onto the surfaces of materials such as iron and steel.
Taking advantage of zinc’s property to preferentially corrode over iron, it is employed for corrosion inhibition. The primary methods include electro-galvanizing and hot-dip galvanizing. Electro-galvanizing involves using electricity to form a uniform and precise thin zinc coating. On the other hand, hot-dip galvanizing immerses the material in molten zinc to create a thick zinc coating, providing excellent corrosion resistance.
Galvanization is used in various fields such as construction, machinery components, and shipbuilding, serving to suppress the corrosion of iron and protect the surface. The advantages include preventing corrosion of iron while imparting a glossy finish, while the disadvantages include variations in corrosion resistance due to the thickness of the zinc and the occurrence of white rust as a result of zinc corrosion.
