Cathodic Protection System
1     Cathodic protection (CP) is a technique used to control corrosion of a metal surface by making it cathodic side of an electrochemical cell
2     Cathodic protection systems are used to protect a wide range of metallic structures in various environments.
3     Most common applications include: Water and fuel pipelines
4     Cathodic Protection (CP) is a technique, used to control corrosion of a metal surface by making it cathode of an electrochemical cell.
5     A simple method of protection connects metal to be protected to a more easily corroded "sacrificial metal" to act as anode.
6     Sacrificial metal then corrodes, instead of protected metal.
7     For structures, such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to provide sufficient current.
8     Cathodic protection systems protect a wide range of metallic structures in various environments. Common applications are: steel water or fuel pipelines and steel storage tanks, such as home water heaters; steel pier piles; ship and boat hulls; offshore oil platforms and onshore oil well casings; offshore wind farm foundations and metal reinforcement bars in concrete buildings and structures.

Cathodic Protection System
Galvanic
1     Another common application is in galvanized steel, in which a sacrificial coating of zinc on steel parts protects them from rust.
2     Cathodic protection can in some cases, prevent stress corrosion cracking.
3     In application of passive cathodic protection, a galvanic anode, a piece of a more electrochemically "active" metal (more negative electrode potential) is attached to vulnerable metal surface, where it is exposed to an electrolyte.
4     Galvanic anodes are selected, because they have a more "active" voltage than metal of target structure (typically steel).
5     Concrete has a pH around 13.
6     In this environment, steel reinforcement has a passive protective layer and remains largely stable.
7     Galvanic systems are "constant potential" systems that aim to restore concrete's natural protective environment, by providing a high initial current to restore passivity.
8     It then reverts to a lower sacrificial current, while harmful negative Chloride ions migrate away from steel and towards positive anode.
9     Anodes remain reactive through their lifetime (10-20 years typically), increasing current, when resistivity decreases, due to corrosion hazards, such as rainfall, temperature increases or flooding.
10     Reactive nature of these anodes makes them an efficient choice.
11     Unlike ICCP systems, steel constant polarization is not goal, rather restoration of environment. Polarization of target structure is caused by electron flow from anode to cathode, so that two metals must have a good electrically conductive contact.
12     Driving force for cathodic protection current is value difference in electrode potential, between anode and cathode.
13     During initial phase of high current, potential of steel surface is polarized (pushed) more negative, protecting steel, which hydroxide ion generation at steel surface and ionic migration restore concrete environment.
14     Over time, galvanic anode continues to corrode, consuming anode material, until eventually it must be replaced.
15     Galvanic or sacrificial anodes are made in various shapes and sizes, using alloys of zinc, magnesium and aluminium.
16     ASTM International publishes standards on composition and manufacturing of galvanic anodes.
17     In order for galvanic cathodic protection to work, anode must possess a lower (that is, more negative) electrode potential than that of the cathode (target structure to be protected).
