Question

Which of the following methods is not used for the prevention of corrosion?

  1. Greasing
  2. Painting
  3. Plating
  4. Heating

hintHint:

Heating involves the presence of oxygen.

The correct answer is: Heating


    • Corrosion is a natural process that transforms a refined metal into a more chemically stable form like oxide, hydroxide or sulphide.
    • Corrosion can be prevented by greasing, painting, plating, galvanizing, alloying.
    • Heating would elevate corrosion as it involves oxygen.
