Cathodic Protection^[1]

This chapter provides a detailed account of cathodic protection. It begins by discussing the fundamentals of cathodic protection followed by a description of the various types of cathodic protection. It then describes the origins, types, and alleged failures of cathodic protection criteria. This is followed by a section providing information on anode materials that are used for cathodic protection applications. General guidelines for designing the cathodic protection systems are also listed. Finally, the chapter presents various examples on cathodic protection of steel structures. The examples are selected to familiarize the design engineer with the steps to follow in selecting a specific corrosion-control method.
