The electrochemistry of corrosion Part 5: prevention and protection

The purpose of this series is to show that there is a basic logic in the science which underlies corrosion and that this logic can lead naturally into a consideration of the methods which are available for preventing corrosion. There are many different methods and combinations of methods which can be used to prevent or reduce corrosion in metals. I have found it convenient to arrange these in separate groups, arranged according to the fundamental principles on which they are based. Practical details of the methods can be found in most textbooks on corrosion.
