Underwater potentiostat for real-time electrochemical corrosion measurements

Corrosion due to seawater studies are urgently required for a safe technology development. Some studies demonstrated that the corrosion rates for most alloys could be four times less than surface corrosion rates. A device for continuous electrochemical measuring of corrosion in real time and underwater is shown in this paper. Therefore, this equipment allows improving the knowledge about long-term materials behavior in this aggressive environment for the scientific community. Also, it has been designed to allow the connection to underwater observatories such as OBSEA.
