Abstract

Galvanic corrosion of buried external metallic surfaces can be controlled and mitigated by proper design, installation, and maintenance of the cathodic protection system. The design criteria typically used by corrosion engineers have been well documented and are supported by successful field applications. Design considerations discussed include selecting the appropriate type of cathodic protection system, electrolyte resistivity, coating quality, and types of anodes available.
