This course describes procedures for designing a cathodic protection system, using a sacrificial anode or an anode with impressed electrical current to prevent electrochemical corrosion.
Electrochemical corrosion is a process by which an electrical current leaves a metal structure (like a buried pipeline or underground tank) at an anode site, passes through an electrolyte (soil or water), and re-enters the structure at the anode site, causing pit corrosion at the anode site. This course describes procedures for designing a cathodic protection system, using a sacrificial anode or an anode with impressed electrical current to prevent electrochemical corrosion.
Topics: introduction to cathodic protection cathodic protection design soil resistivity measurement current requirement testing example of "galvanized" and "impressed current" cathodic protection design specifications for ceramic anodes rectifier current interference
Intended Audience: for civil, mechanical, construction, electrical, and industrial engineers.
