Abstract

Dispositif potentiométrique de préservation et anticorrosif empêchant des organismes marins d'adhérer à une surface conductrice immergée dans de l'eau saumâtre ou de l'eau de mer. Une électrode de titane constitue une anode; une couche d'oxyde diélectrique formée électriquement sur l'électrode limite le passage de courant à partir de la surface immergée. L'électrode est montée au voisinage de la surface conductrice et isolée de celle-ci. Une alimentation applique une différence de potentiel entre l'électrode de titane et la portion de surface conductrice immergée, qui est rendue cathodique par rapport à l'anode par le potentiel appliqué et est donc protégée contre la corrosion et le salissement. Protection des coques de navires.Potentiometric preservation and anticorrosive device preventing marine organisms from adhering to a conductive surface submerged in brackish water or sea water. A titanium electrode constitutes an anode; a dielectric oxide layer electrically formed on the electrode restricts the flow of current from the submerged surface. The electrode is mounted in the vicinity of the conductive surface and insulated from the latter. A power supply applies a potential difference between the titanium electrode and the submerged conductive surface portion, which is rendered cathodic with respect to the anode by the applied potential and is therefore protected against corrosion and soiling. Protection of ship hulls.
