Question
Write some measures to prevent rusting.
Answer
Here are some measures to prevent rusting:
- Coating: Coating the metal surface with a protective layer, such as paint, enamel, or varnish, can prevent rusting by isolating the metal surface from the atmosphere.
- Galvanization: Zinc coating or galvanization can be used to protect iron or steel surfaces from rusting. Zinc is more reactive than iron, so it corrodes first, protecting the underlying iron.
- Alloying: Adding small amounts of other metals, such as chromium or nickel, to iron or steel can improve its resistance to rusting.
- Oil or grease: Applying a thin layer of oil or grease to the metal surface can prevent the metal from coming into contact with water or air, preventing rusting.
