d6s74no67skb0.cloudfront.netThus, the galvanic cathode protection system is called a sacrificial anode cathodic protection system because the anode corrodes sacrificially to protect the structure. Galvanic anodes are usually made of either magnesium or zinc because of these metals’ higher potential compared to steel structures.

An Introduction to Sacrificial Anode Cathodic Protection
pdhonline.comcurrent cathodic protection systems. The high potential electrons are generated through the corrosion of an active metal such as magnesium or zinc. In this type of system, the anode material is consumed, or sacrificed in the process, and the anodes must be periodically replaced
Cathodic Protection Field Installation Guide-NEW
www.usbr.govCathodic protection is a means of reducing corrosion of a metal by artificially causing direct current to flow from external anodes, through the electrolyte (soil or water), and onto the structure to be protected. The two types of CP systems are galvanic anode and impressed current. Galvanic anode CP systems provide cathodic current by galvanic ...
