Coating metals/Protecting metals from corrosion

• Steel has many uses for example construction and to make utensiles
• This is because it is cheap and strong
• It is however susceptible to rusting
• This is because it combines with the oxygen in the air
• This results in the formation of iron oxide which is soft and crumbles
• Like steel other metals also corrode when they are exposed to air
• To ensure the strength, cleanliness and usefulness of steel and these metals
• Several ways are used to stop, prevent and minimize rusting and corrosion
• These methods include:
• Galvanising
• Electroplating using copper, tin, chrome or nickel
• Oiling
• and painting
