Cathodic protection is a way of preventing or controlling corrosion of a metal structure.
Cathodic protection is used to control corrosion of metal on the surface of structures in various environments. In some cases Cathodic protection can prevent stress corrosion and fracturing.

A cathodic inhibitor is a type of corrosion inhibitor, a chemical compound that, when added to a fluid or gas, decreases the corrosion rate of a metal or an alloy. An example of a cathodic inhibitor is zinc oxide, which retards the corrosion by inhibiting the reduction of water to hydrogen gas. As every oxidation requires a reduction to occur at the same time it slows the oxidation of the metal. As an alternative to the reduction of water to form hydrogen, oxygen or nitrate can be reduced.

The KKS system is a standardized system for the classification of technical equipment in power plants. It does not specifically address cathodic protection systems. Cathodic protection systems are typically classified based on their method (e.g., impressed current or sacrificial anode) and location within the power plant.

Cathodic protection - attach a piece of zinc Cathodic protection - pass electric current through it - take care this is an industrial method only for protecting pipelines etc. Galvanizing Painting Wax/oil/grease

A cathodic protection program is a preventative maintenance program to ensure cathodic protection systems at a facility are maintained and tested in a cost effective, regular interval and remedial repairs are performed in a timely manner.A well run program should include budgeting and personnel for the following:Training for technical personnelMonitoring of CP system by on-site personnelAnnual surveys by CP expertsOn call services of corrosion technical experts to inspect corrosion failuresOn call services of corrosion technical experts to help design remedial repairsPeriodic CP system repairs.Records maintenance for inspection by regulatory agencies and maintenance personnel.NACE International www. nace.org maintains a directory of technical experts in cathodic protection.Mawhinney Corrpro
Steel and and iron can be protected by coating with zinc (galvanizing) or alloying with chromium or just simply painting it every once in a while. Cathodic protection is also extensively used to protect against corrosion.
