摘要： Esta tecnologia refere-se a um sistema de proteção contra corrosão baseado na formação e manutenção do filme apassivador protetor. A tecnologia inclui um conversor que pode funcionar com fontes de alimentação híbridas e possui elementos capazes de mitigar o problema de correntes de proteção elevadas que podem surgir quando o filme condutivo existente na superfície metálica a proteger tiver um índice de condutividade muito elevado. A tecnologia também possui maior resiliência a variações de tensão, propiciando menor ocorrência de falhas e maior estabilidade do sistema quando a tensão de entrada das fontes de alimentação apresentam variações indesejadas. A tecnologia utiliza técnicas de PWM ("pulse width modulation" ou modulação por largura de pulso) em duplo estágio sequencial aplicados ao conversor e também utiliza um material isolante para recobrir as estruturas e reduzir a condutividade o filme condutivo existente na superfície metálica a proteger. Além disso, seu espectro de utilização é opcionalmente adaptado para a condução da corrente de proteção pelo filme condutivo também em atmosferas explosivas. A tecnologia aplica-se no contexto da proteção contra corrosão de superfícies metálicas como, plataformas marinhas, embarcações e estruturas em geral que estejam submetidas a ambientes marinhos ou em banhos.

摘要： In a method for cathodically protecting and/or passivating a metal section in an ionically conductive material such as steel reinforcement in concrete or mortar, an impressed current or sacrificial anode communicates electrical current to the metal section and a storage component of electrical energy which can be a cell, battery or capacitor is provided as a component of the anode. The storage component can have replacement energy introduced by re-charging or replacing the component from an outside supply. Typically the cell or storage capacitor has an outer case which carries an anode material as an integral outer component.

摘要： An electrical connector for an anode has a terminal for an electric cable, at least two magnet devices for attracting the connector onto a metal structure, a plate electrically connecting the magnet devices to one another and to the terminal, and a deformable member connecting the magnet devices. When the connector connects an anode to a surface, the magnet forces draw the magnet devices against the surface in order to make up the connection. The deformable member allows relative movement of the magnet devices, permitting them to align themselves in an optimum configuration to maximise the surface area of the magnet devices that are in contact with the metal structure, providing a large electrical conduit between the connector and the cable connected to the terminal, and allowing for more reliable electrical connection between the anode and the structure.

摘要： This assembly provides a flexible method of attaching discrete sacrificial anodes to exposed steel in concrete construction to achieve an advantageous distribution of protection current. It comprises a base metal [1] that is less noble than steel, a conductor [6] connected to the base metal, a tying point [2] formed at least in part by the conductor, and a tie [4] that passes through the tying point [2] and around the steel [5]. The tie is used to physically tie the anode between steel bars prior to placing the concrete and in the process to electrically connect the anode to the steel. The tying point is open to facilitate adjusting the tie. The separation of the tie from an anode assembly with a tying point allows the tie to be selected during installation when the properties required by the application are known.

摘要： A corrosion protection device, system, and method are provided. The device may operate while being coupled to the object being protected and to a power source using a total of only two terminals. This may be accomplished by de-referencing the return path node of the circuit using a choke device that blocks a temporal AC component of an anti-corrosion signal. The choke device therefore diverts the anti-corrosion signal to a single negative/ground path to the object and then returns through a positive lead of the circuit. A two terminal corrosion protection device may thereby simplify the installation process, for example on a vehicle, by not requiring that another connection be made to the object at a spaced apart location from a first connection to the object.
