118 Methods Of Corrosion Prevention

It was shown earlier that a corrosion cell consists of four components: an anode, a cathode, a conducting electrolyte, and a metallic conducting circuit. This knowledge provides us with an understanding of how to minimize or prevent corrosion. Corrosion prevention strategies are therefore based on one of the following approaches:

1. Reduce the aggressiveness of the environment/adding inhibitors

2. Apply cathodic or anodic protection

3. Apply a protective coating to the substrate

4. Appropriate material selection

5. Application of good design principles

Approaches 4 and 5 will be dealt with in Sections 11.9 and 11.10.
