katoodkaitset
Katoodkaitset, also known as cathodic protection, is a technique used to prevent corrosion of a metal surface by making it the cathode of an electrochemical cell. This is achieved by supplying a direct current to the metal structure. The current can be supplied by a sacrificial anode, which is a more reactive metal that corrodes instead of the protected structure, or by an impressed current system that uses an external DC power source.
The principle behind cathodic protection is to shift the electrochemical potential of the metal to a more
Cathodic protection is widely used to protect a variety of metal structures, including pipelines, storage tanks,
