This course reviews the concepts involved in providing cathodic protection. Cathodic protection is a technique to control the corrosion of a metal surface by making it work as a cathode of an electrochemical cell. Corrosion is an electrochemical process in which a current leaves a structure at the anode site, passes through an electrolyte, and re-enters the structure at the cathode site.

The basics of cathodic protection are reviewed as well as how cathodic protection systems operate. The course includes examples of a design of a simple galvanic and impressed current system.

After taking this course the learner will have an understanding of the following topics:

• The basics of cathodic protection
• The pertinent tests for cathodic protection
• The design process for a galvanic cathodic protection system
• The design process for an impressed current cathodic protection system
