摘要： A system for electrochemical treatment of reinforced concrete comprises a plurality of power supply units (1a, 1b, 1c, 1d, 1e) for delivering electrical power to the concrete. Each power supply unit is connected, through a multiplexer (2), to a computer (3) programmed to control the setting up of the system and its operation. Each power supply unit has a microprocessor which includes non-volatile memory in which is stored the history of output current and anode/cathode potential and which is accessed at intervals by the computer (3).

摘要： The present invention relates to a method for cathodic protection of steel reinforced concrete which comprises using an anode structure made of an array of valve metal strips activated by an electrocatalytic coating and having voids therein, supported by or inserted into insulating spacers, said strips being connected by connection means either provided with voids or without voids, or rods, bars, insulated cables. The anode structure is applied to the reinforcing steel cage during construction before the concrete is poured. The anode structure of the present invention exhibits a remarkable mechanical resistance and has an anode surface which may be tailored in order to provide for the necessary protection current on the basis of the density of the reinforcing bars contained in the structure to be cathodically protected.

摘要： Electrodes for electrochemical processes, especially anodes for the cathodic protection of metal substrates, e.g. reinforcing bars in concrete, comprise a conductive core (11) which acts as a current-distributing member, an outer member (13) which provides an electrochemically active outer surface, and an intermediate member (12) composed of a material which is of higher resistivity, and/or which is less electrochemically active, than the material of the outer member. The higher the resistivity of the intermediate member, the more regular the current distribution along the length of the electrode. When the intermediate member is less electrochemically active, this protects the core from corrosion if the outer member is damaged by physical means or through electrochemical erosion. Preferably at least one of the intermediate member and the outer member is composed of a conductive polymer, especially one comprising carbon black or graphite as conductive filler.

摘要： A catalytic polymer electrode comprises a current conducting polymer body forming an electrode base which is provided with catalytic valve metal particles fixed to its surface. A current conducting body of carbon filled thermoplastic polymer is heated to soften its outer surface, and the catalytic valve metal particles are pressed onto its softened surface and thereby attached to the surface of the polymer body. Such a catalytic polymer electrode used as an anode in an impressed-current cathodic protection system comprises a catalyst to provide a reduced oxygen potential. Such catalytic polymer anodes may be applied in systems for impressed current cathodic protection of reinforced concrete structures, such as bridge decks, support members, parking garages, or of buried or submerged steel structures such as gas and oil pipelines, offshore production platforms, fuel storage tanks, well casings.

摘要： An anode for cathodically-protected steel-reinforced concrete is embedded in an ion-conductive overlay on the concrete structure. The anode comprises at least one sheet of highly expanded valve metal mesh having a pattern of voids defined by a network of valve metal strands (3, 22) connected at a multiplicity of nodes (25). This provides a redundancy of current-carrying paths through the mesh which ensures effective current distribution throughout the mesh even in the event of possible breakage of a number of individual strands. The surface of the valve metal mesh carries an electrochemically active coating. At least one current distribution member (23) is welded to the valve metal mesh. The entire area of the structure to be protected, excluding non-protected openings for obstacles and the like, is covered by a single piece of the mesh, or several pieces in close proximity with one another. The system is installed by providing a roll (32) of coated valve metal mesh (30), unrolling the mesh and installing it in conformity with the structure (40), fixing the mesh to the structure and embedding the mesh in an ion-conductive overlay.

摘要： Bloc de lestage/contre-poids (1) en deux parties de type connu- rond (circulaire), carré comme on voit sur le dessin, hexagonal, octogonal ou de toute autre forme géométrique externe- avec des anodes métalliques incorporées (4) destinées à être placées à proximité immédiate des boulons de métal (3) servant à assembler et à fixer les blocs de lestage/contre-poids (1) sur une conduite (2) destinée à être disposée sur ou dans le fond de la mer ou d'un lac. Les anodes incorporées (4) sont ainsi placées dans le sens longitudinal des boulons (3), très près desdits boulons (3) que les anodes (4) sont destinées à protéger contre la corrosion, de telle sorte que le champ galvanique de contraintes devient minimal. La conformation des anodes (4) en tuyaux, qui sont incorporés dans le bloc de lestage (1), assure en outre que les longs trous de boulons ménagés dans le bloc de lestage (1) sont bien rectilignes et de forme stable. Les anodes (4) qu'on voit sur le dessin sont sous forme de tuyaux cylindriques, mais elles peuvent être fabriquées sous n'importe qu'elle autre forme de section transversale géométrique, telle que barres profilées et autres. De même, lesdites anodes incorporées peuvent être fabriquées selon une toute autre conformation de section que celle qu'on voit sur le dessin, telle que manchons ou barreaux, disposées dans les longs trous de boulons, éventuellement directement sur les tiges même des boulons.
