TeachMeFinance.com - explain Cathodic protection Cathodic protection The term 'Cathodic protection' as it applies to the area of reclamation can be defined as ' An electrical system for prevention of rust, corrosion, and pitting of metal surfaces which are in contact with water or soil. A low-voltage current is made to flow through a liquid (water) or a soil in contact with the metal in such a manner that the external electromotive force renders the metal structure cathodic. This concentrates corrosion on auxiliary anodic parts which are deliberately allowed to corrode instead of letting the structure corrode'.
