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 the procedures for designing a cathodic protection system, using a sacrificial anode or an anode with impressed electrical current to prevent electrochemical corrosion.

    This course is intended for civil, mechanical, chemical, construction, environmental, electrical, and industrial engineers. An attendee of this course will gain knowledge about electrochemical corrosion and procedures for providing protection from it.

    In this course, you need to review the material in the Department of the Army Technical Manual No. 5-811-7, "Electrical Design, Cathodic Protection"

    Upon completing your review of the course material, you need to take a multiple choice quiz consisting of twenty (20) questions to earn 4 PDH credits. The quiz will be based on the entire document. 80% correct is required for a quiz passing grade.
