Firsts underwater potentiostat sea-tests in the OBSEA

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 has been
designed. Therefore, this equipment allows improving the knowledge about longterm
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. In this paper we expose the first tests have been conducted in a real
environment such as OBSEA.
