AN ATTEMPT FOR PROVIDING SIMULTANEOUS CATHODIC PROTECTION AND ANTI-FOULING OF SHIPS IN SEA WATER

An attempt was made to protect the ship's hull from corrosion and marine growth at the same time, by applying impressed current cathodic protection system based on the use of titanium anodes with modified RuO2-TiO2 coating. Simultaneous cathodic protection and anti-fouling were provided by electrochemical reaction of hypochlorite production which takes place on this coating with a current efficiency of 95% during cathodic protection. It was found that, although the protection current was rather small (30 A), there was no corrosion of the hull after applying this system on the ship for a period of eight months, while the process of marine growth was considerably diminished. Further investigations in this field are in progress.
