Abstract
La présente invention concerne un objet métallique qui doit être protégé de la corrosion, tel qu'un panneau de carrosserie d'automobile en acier, et qui est raccordé à une source d'électrons telle qu'une cathode. Un revêtement électro-isolant est disposé sur l'objet métallique. Une anode de recouvrement est appliquée sur le revêtement électro-isolant. L'anode de recouvrement est électroconductrice. Une électrode est raccordée à l'anode de recouvrement et à la source d'électrons. Des dégâts à l'anode de recouvrement et au revêtement électro-isolant créent un emplacement pour un électrolyte à collecter afin de créer une cellule électrochimique et d'activer une protection cathodique pour empêcher la corrosion de l'objet métallique.
