Which of the following methods is not used to coat metallic elements to prevent corrosion?

• A. Electroplating
• B. Metal cladding
• C. Metal spraying
• D. None of the above

Answer 1

The correct option is D None of the above

Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes or to prevent corrosion of a metal. Metal cladding is the bonding together of dissimilar metals. It is different from fusion welding or glueing as a method to fasten the metals together. In metal spraying a wide range of metals is sprayed onto the surface of another metal. All of these methods are used to prevent corrosion.
