Step 1
How can the rusting of steel be prevented?
Answer
To prevent the rusting of steel, various methods can be employed. These include:
- Oiling: Covering steel with oil creates a barrier against moisture and air.
- Painting: Applying a coat of paint seals off steel from the environment, thus preventing rust.
- Galvanising: This process involves coating steel with a layer of zinc, which provides protection against corrosion.
- Electroplating: Similar to galvanising, it involves depositing a thin layer of another metal that shields the steel.
- Plastic Coating: A plastic layer can be applied to the steel surface to protect it from environmental damage.
