A technique used to minimize the rate of corrosion of a structure. Cathodic protection does not eliminate corrosion, it transfers corrosion from the structure under protection to a known location wher [..]

Cathodic protection is a method of protecting metallic pipelines from corrosion. Technically speaking: Cathodic protection is a method of corrosion prevention in which the pipeline is allowed or made to act as the cathode in an electrochemical corrosion cell. A sacrificial anode having a lower electrolytic potential than the pipe is provided to com [..]

A technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. The simplest method to apply CP is to connect the metal to be protected to a piece of [..]

A method of preventing oxidation (rusting) of exposed metal structures, such as bridges and pipelines, by imposing between the structure and the ground a small electrical voltage that opposes the flow [..]

A technique used to prevent corrosion of metal by making the metal a cathode.

method of preventing corrosion of iron or steel by suspending stainless steel anodes in the tank and passing a small current continuously through the system.

A technique to prevent corrosion of a metal surface by making it the cathode of an electrochemical cell.

A technique to prevent corrosion of a metal surface by making it the cathode of an electrochemical cell.

The protection of metals from corrosion by electrochemical techniques. If when a vessel is in a shipyard you see several gray unpainted blocks of metal attached to the hull, especially near the propeller, these are part of the cathodic protection system. These blocks are called zinc plates and as electrolysis when present will attack the softest me [..]

The reduction or prevention of corrosion of a metal surface caused by making it cathodic. This is accomplished by using a sacrificial anode (such as in zinc rich coatings or galvanizing) or by using i [..]

Sacrificial or impressed current system of corrosion protection of hull, tanks and piping.

Protection of a ship's hull against corrosion by the use of impressed electric current or by sacrificial anodes

An electrical system for prevention of rust, corrosion, and pitting of metal surfaces that are in contact with water, wastewater, or soil. A low-voltage current is made to flow through a liquid (water [..]

A technique to prevent the corrosion of a metal surface by making that surface the cathode of an electrochemical cell.

ka-thod-ik pruh-tek-shuhn Method used to minimise rate of electrochemical corrosion of structures, for example, installations offshore, pipelines and storage tanks.

Protection against environmental corrosion (soil or moisture) of underground or submerged metallic structures through the use of a negative potential applied by an external source to the structure.

A method of preventing corrosion by applying a low-voltage electrical charge on a metal pipeline, which causes the pipeline to behave as a cathode

A technique to prevent the corrosion of a metal surface by making that surface the cathode of an electrochemical cell.

Reduction of corrosion rate by shifting the corrosion potential of the electrode towards less oxidizing potential by applying an external electromotive force.

the prevention of corrosion by making the metal to protect a cathode; this is because when corrosion occurs in an electrolyte corrosion cells are set up causing electric currents to flow out from anodes to cathodes; the anodes give itself up or corrode and the cathodes receive current or get protected; on a ship cathodic protection is applied on th [..]
