3. Master the Fundamentals of Cathodic Protection
The course provides an overview of cathodic protection (CP) systems, covering fundamentals like CP mechanisms, electrolytes, and components of sacrificial anodes and impressed current systems. Learners will understand the impact of applied currents on corrosion and how to measure a structure’s potential using reference electrodes and voltmeters. The course addresses practical considerations such as ohmic effects, electrochemical reactions, CP system design, and avoiding overprotection. Topics include potential gradients, current distribution, remote anodes, evaluating current distribution, stray current corrosion, anode resistance, groundbed properties, current drain tests, and coatings' impact on CP requirements. n.
