Galvanic corrosion cannot be prevented by___________________?
Correct answer: B. Anodic protection
- A. Cathodic protection
- B. Anodic protection
- C. Usage of largest possible anodic area
- D. Any one of these
Explanation
Cathodic protection makes the metal surface a cathode, while using a large anodic area reduces the anodic current density. Anodic protection is mainly used to passivate suitable metals in specific environments, not as a general prevention method for galvanic corrosion.
