摘要： Corrosion protection of steel in concrete is provided by locating an anode assembly including both a sacrificial anode and an impressed current anode in contact with the concrete and providing an impressed current from a power supply to the anode. The impressed current anode forms a perforated sleeve surrounding a rod of the sacrificial anode material with an activated ionically-conductive filler material between. The system can be used without the power supply in sacrificial mode or when the power supply is connected, the impressed current anode can be powered to provide an impressed current system and/or to recharge the sacrificial anode from sacrificial anode corrosion products.

摘要： A coating for a metal surface that provides excellent resistance to both electrochemical corrosion and mechanical insult is provided. The coating involves at least an inner coating that is a sacrificial anodic layer and an outer coating that is a protective dielectric material made of inorganic metal oxide. Some versions of the coating include an intermediate layer as well that serves to improve adhesion between the coatings and may provide additional galvanic protection. Although the coating can be made by a variety of methods, advanced methods of spray application are provided for making high-quality lightweight versions the coating.

摘要： The exemplary embodiments relate to a multilayer aluminum alloy sheet material suitable for fabrication into coolant-conveying tubes, headers and the like used for heat exchangers, and to the tubes and headers, etc., fabricated from the sheet. The multi-layer metal sheet has a core layer of aluminum alloy having first and second sides. The first side has an interlayer made of a Zn-containing aluminum alloy positioned between a Zn-containing outer layer and the core layer. The alloy of the outer layer is more electronegative than the alloy of the interlayer. The alloy of the interlayer is preferably more electronegative than the alloy of the core layer. The first side clad in this way is the side intended for exposure to the coolant, and provides good resistance to corrosion and erosion.

摘要： A method of coating a magnesium-based substrate includes applying a first potential of electric current to the substrate and, after applying, immersing the substrate in an electrocoat coating composition. After immersing, a second potential of electric current is applied between the substrate and a counter electrode to deposit the electrocoat coating composition onto the substrate. The second potential is greater than the first potential. The method also includes curing the electrocoat coating composition to form a cured film and thereby coat the substrate. An electrocoat coating system includes the magnesium-based substrate, and the cured film disposed on the substrate and formed from the electrocoat coating composition. The substrate exhibits a negative charge from an applied first potential of electric current of ≦ approximately 40 V prior to contact with the electrocoat coating composition. The magnesium-based substrate is substantially free from magnesium dissolution when in contact with the electrocoat coating composition.
