What is KKS? Cathodic corrosion protection is a process in which a metal is protected against corrosion by forcing it to undergo a cathodic reaction. By using an external power source, the metal is turned into a negative pole (cathode), which protects it from corrosion. This is done by shifting the corrosion potential of the metal to a lower level, which slows down or even stops the corrosion process. By using these protective measures, the service life of the structure can be extended and protection against corrosion can be guaranteed. The artificial current causes the metal to emit electrons, which are provided by the current source. This reduces or prevents the formation of corrosive products. The metal is put into a protected state, as it no longer becomes the anode where corrosion takes place. KKS cathodic corrosion protection is often used for metal structures that are exposed to corrosive environments such as water or soil. The use of this protective measure can extend the service life of the structure and ensure protection against corrosion.The huge advantage of KKS is the minimal intervention in the structure, monitoring from outside and the elimination of supports and reduction of downtimes and closures.
