• CO2 corrosion

• Atmospheric corrosion

• Seawater corrosion

3. Which degradation is not part of ‘internal’ corrosion?

• Stray current corrosion

• CO2 corrosion

• Dissolved oxygen corrosion

4. What type of cracking is SCC (Stress Corrosion Cracking) ?

• Anodic type

• Cathodic type

• Mechanical damage

5. What are typically corrosion barriers for seawater and soil external corrosion?

• Corrosion Inhibitor and corrosion allowance

6. How does cathodic protection principles work?

• Blocking the exposure of water to the metal

• Removing all corrodents from the electrolyte

• Providing physical barrier of the water and corrodent

• Making the steel surface ‘cathodic’ and providing alternative anode
