Principle of cathodic protection

Corrosion is the spontaneous chemical reaction of a metal against its surroundings. Particularly, in sea water this chemical reaction proceeds by an electrochemical mechanism involving oxidation of the metal, which results in metal loss. That happens when we have a plate with pitting appearance, at the spots where the coating is not good enough to protect.

The part of the metal surface in the electrochemical mechanism (electron release) is called anodic. The other part of the metal surface where the electron consumption takes place is called cathodic.

                         The Innovative Cadmium Free Anodes 

At Katradis we are committed to environmental sustainability and we have achieved the development of a novel zinc anode alloy devoid of cadmium, in collaboration with the National Technical University of Athens. This achievement was guided by their valuable insights and facilitated by a series of experiments conducted within our R&D department.
