Title (EN) CATHODIC PROTECTION OF METAL SUBSTRATES
(FR) PROTECTION CATHODIQUE DE SUBSTRATS MÉTALLIQUES
Abstract:
(EN) The present invention generally provides a system for metal corrosion protection, including a metallic object to be protected, connectable to an electron source as cathode, an electrically isolating coating disposed on at least a portion of the metallic object, an electrically conductive blanket anode applied on at least a portion of the electrically isolating coating; an electrode electrically connected to the blanket anode and connectable to the electron source. The present invention further proposes a kit for providing corrosion protection to a substrate and method thereof.
(FR) La présente invention concerne de manière générale un système de protection contre la corrosion de métaux, comprenant un objet métallique à protéger, pouvant être connecté à une source d'électrons en tant que cathode, un revêtement électriquement isolant disposé sur au moins une partie de l'objet métallique, une anode de type couverture, électroconductrice, appliquée sur au moins une partie du revêtement électriquement isolant ; une électrode connectée électriquement à l'anode de type couverture et pouvant être connectée à la source d'électrons. La présente invention propose en outre un kit de protection contre la corrosion d'un substrat, et un procédé associé.
