Question
Which of the following methods is not used for the prevention of corrosion?
- Greasing
- Painting
- Plating
- Heating
Hint:
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.
