उत्तर
Corrosion of metals can be prevented by the following methods:
- Applying coatings: Metals are coated with oil, grease, varnish, or paint to prevent direct contact with air and moisture.
- Metal plating: Metals are plated with a non-corroding metal. For example, zinc plating (galvanization) is used to protect iron from rusting.
