In addition to safety and environmental aspects, cathodic protection (CP) offers the optimum protective measure for structures in addition to passive protection (e.g. coatings). The principle of cathodic protection is based on reversing the corrosion process, thereby reducing ...https://martin-gmbh.de/wp-content/uploads/MARTING-GmbH-KKS-Skizze.png
