    Abstract: Anti-corrosion nanoparticle compositions include a carrier and a plurality of nonionic metal nanoparticles. The metal nanoparticles can be spherical-shaped and/or coral-shaped metal nanoparticles. The nanoparticles are selected so as to locate at the grain boundaries of a metal or metal alloy when the anti-corrosion composition is applied to the metal or alloy, thereby reducing or preventing intergranular corrosion of the metal or alloy.

    Abstract: Disclosed is an anode assembly for the corrosion protection of metal parts embedded in concrete. An ion-conducting material is placed between the metal part that is to be protected and the anode, which ion-conducting material exhibits higher ionic conductivity than the surrounding concrete, thus directing the protective current specifically towards the metal part. A galvanic sacrificial anode may be provided, made, e.g., from zinc and its alloys or aluminum and its alloys. The purpose of the material with higher ionic conductivity than the surrounding concrete is to selectively direct the protective galvanic current towards the metal part that is to be protected. The selective enhanced corrosion protection is especially beneficial for the protection of metal parts that are highly important for the structural integrity of concrete members, such as assembly of pre- or post-tensioning of concrete members, such as anchor-heads. The ion conducting material exhibits 20%, and more preferably 50%, higher conductivity than the surrounding concrete. A suitable ion-conducting material that exhibits ion-exchange properties may comprise tecto-alumo-silicate materials. The anode may be placed in close contact to or may be embedded into the ion-conducting material as well.

    Abstract: Galvanic anodes and barrier corrosion control for metal pipelines, tanks, and equipment under thermal insulation includes the use of pure aluminum and aluminum alloys in fresh water at high temperatures to protect steel elements in hot water without sufficient chlorides. Sacrificial aluminum and sacrificial zinc-aluminum powders in a mixed primer provide long-term, effective corrosion control of steel under thermal insulation can be achieved in all water temperature ranges regardless of the presence of sufficient chlorides. At temperatures below 75° C., the zinc particles in the primer act to protect the substrate steel. At temperatures above 75° C., the aluminum particles in the primer, and galvanic aluminum tape protect the substrate steel in chloride free neutral pH water and also reduce the consumption of zinc particles in the primer. When the electrolyte water for CUI is sufficiently contaminated with chlorides, the aluminum particles in the primer and the galvanic aluminum become active.

    Abstract: A cathodic protection device enclosing a reference cell and a conductive media and having two coupon assemblies mounted, facing opposing direction, on an exterior surface. The coupon assemblies each have a disc-shaped coupon seated in a coupon jacket and are electrically coupled to a wire. The coupon jacket defines a pocket in a first surface and a groove in a second, opposing surface thereof. The disc-shaped coupon is seated in the pocket and the wire is seated in the groove with the electrical junction therebetween aligned with an aperture connecting the pocket to the groove. A sealing material is used to form a watertight seal between the disc-shaped coupon and the pocket and fills the groove. The device includes a hydrophilic porous member having a first surface in communication with the conductive media and a second surface in communication with an external environment.
