There are two ways to prevent the rusting of iron:
Coating with a protective layer: Iron can be protected from rusting by applying a coating of paint, oil, or grease. These coatings act as a barrier between the iron and the surrounding environment, preventing moisture and oxygen from coming into contact with the iron surface.
Galvanization: Galvanization is a method of protecting iron from rusting by coating it with a thin layer of zinc. This process forms a protective barrier on the surface of the iron, preventing the corrosive elements from reaching the iron and causing rust. Even if the zinc coating gets damaged, the iron underneath remains protected.
These methods effectively prevent the rusting of iron and help to maintain its durability and appearance.
