    摘要: The present invention develops dies, moulds, tools, workpieces and structures with active protection against corrosion (cathodic protection) in cooling circuits, often internal, independent of its complexity. Moreover, the protection can be renewed if considered appropriate. The protection is achieved through a thin coating layer which contains metallic elements more electronegative than the substrate to be protected and which is properly adhered to the mentioned substrate in order to ensure an efficient cathodic protection.

    摘要: An electrolytic mortar for fabricating galvanic anode panels is strengthened with fibers to improve green strength and resistance to cracking. Elongated reinforcing fibers are introduced into a flowing stream of mortar and deposited in multiple layers upon a platen or mold. A sacrificial zinc anode of open construction is embedded between the multiple layers to allow for electrolytic conduction between the layers and over all surfaces of the zinc anode.

    摘要: The galvanic cathodic protection of reinforced concrete structures such as bridges, buildings, parking structures, piers, and wharves, is enhanced by the use of an inert water absorbent solid. The absorbent solid and chemicals are mixed with a cementitious binder to form an activating matrix. This matrix surrounds a sacrificial metal anode such as zinc, or aluminum or their alloys. The metal anode is electrically connected to the ferrous reinforcing member by a metallic conductor. The water absorbent solid may be a clay such as bentonite or a hydrated mineral such as vermiculite. It is preferably in the form of discrete particles dispersed throughout the binder. The inclusion of the absorbent solid in the activating matrix serves to increase the protective current, thereby reducing corrosion of the reinforcing components of the concrete structure.

    摘要: The invention relates to a process of reducing scaling of a metal surface exposed to an aqueous solution from which scale may form after a period of exposure. The process comprises applying a cathodic potential to the surface for at least some of the period of exposure. In some cases, e.g. when an article is made of a ferrous metal, it is advantageous to coat the article with a different metal (e.g. copper or an alloy of copper) before applying the cathodic potential to avoid hydrogen generation and excessive current flow. An article to be protected from scaling may also advantageously be electrically isolated from other parts of an apparatus.

    摘要: An ionically conductive agent having means for reducing passivation of metal subject to anodic dissolution is disclosed. The ionically conductive agent (30) is interposed between metal to be protected from corrosion (60) and metal to be sacrified (20) to provide cathodic protection. An electrical connection (80) between the two metals completes a galvanic circuit. The means for reducing passivation can be either a complexing agent (40) for ions of the metal to be sacrificed or can be a membrane to inhibit flow of ions that would affect the ability of the ionically conductive medium to support continued anodic metal dissolution. The ionically conductive agent and a system for cathodic protection using the ionically conductive agent is particularly suitable for a galvanic circuit to cathodically protect reinforcement bars in concrete structures such as transportation bridges, transportation highways, parking facilities, and balconies exposed to corrosive environments.

    摘要: A method for electric protection of a metal object consists in that an extended grounding electrode is placed into an electrolytic medium at a determined distance from the metal object to be protected, the grounding electrode and the object are connected to an electric power source so as to provide for a protection circuit and the metal object is polarized. The electric connection sections and the geometric dimensions and/or electric parameters of the electrode are chosen so that the value of the current propagation constant in the protection circuit does not exceed 10 m . The grounding electrode comprises an extended central flexible metal conductor (18), an adhesive layer (20) providing for electric contact and an envelope (19) of a hardly soluble polymer current-conductive material based on a composition including a carbon-containing filler 40-80 % by weight, a rubber-based polymer 10-49 % by weight, a plasticizer 9-10 % by weight and an insecticide 0,2-10 % by weight.

    摘要: Effective processes of preventing the oxidation of metal objects by capacitive coupling. These processes are particularly suited to preventing the oxidation of metal objects which are not grounded to the earth, such as automobiles and trucks. These processes significantly reduce the rate of oxidation of such metal objects. An electric current is impressed into the metal object by treating the metal object as the negative plate of a capacitor. This is achieved by a capacitive coupling between the metal object, a dielectric material and a positive plate. Pulses of direct current are provided to the positive plate. The metal object has a common ground with the means for providing the pulses. When the metal object is not grounded to the earth, then the preferred process includes means to provide an electrical connection between the positive plate and the earth ground through a high voltage diode which is adapted to allow the flow of electrons from the earth ground to the positive plate but prevent the flow of electrons from the positive plate to the earth ground.
