WebThe designing of cathodic protection systems is rather complex, however, it is based on simple electrochemical principles described earlier in Chapter 2.Corrosion current flows between the local action anodes and cathodes due to the existence of a potential difference between the two (Fig. 5.1).As shown in Fig. 5.2, electrons released in an anodic reaction … Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead of the protected metal. For structures such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to …
