Corrosion Control by Anodic Protection

The technique of cathodic protection is well known and has been widely applied to a number of corrosion problems. It is not so well known that corrosion can also be prevented in suitable cases by anodic protection, using a platinum electrode system. The author shows that, with adequate laboratory work beforehand and proper instrumentation, the use of anodic protection can make an effective contribution to the life of a chemical plant.
