Passive Cathodic Protection at Phillip Dorsey blog

Passive Cathodic Protection. In passive cathodic protection systems, the sacrificial anode is connected directly or indirectly to the metal to be protected. Learn how cathodic protection prevents corrosion on submerged and underground metallic structures by converting active areas to passive. There are two types of cathodic protection: The decreased dc current density prevents polarization into immunity and cathodic dissolution of the protective passive film, thus. F two simultaneous chemical reactions. The potential difference between the two dissimilar metals generates adequate electricity to form an electrochemical cell and drive galvanic or bimetallic corrosion. Depending on the technology used, it is possible to implement passive cathodic protection with coatings and inhibitors, or active cathodic protection using sacrificial anodes or impressed current to counteract faults and gaps in the coating caused during installation or by deterioration. Both provide a cathodic protection current flow from cathodic protection anodes placed within the same electrolyte as the metal to be protected. Galvanic anode and impressed current cathodic protection.
