The Activity of Trace Metals in Aqueous Systems and the Effect of Corrosion Control Inhibitors.

摘要

Water as a dielectric offers many advantages in high energy density electrical storage systems, particularly when pressurized. As part of a continuing research program in high energy density storage research, the water purification system at Kirtland Air Force Weapons Laboratory was monitored in order to determine the electrical and corrosive characteristics of the water and to investigate its use as a dielectric medium for capacitors. The specific conductance, pH, and the analysis of ionic impurities were used as the basis for evaluating the water purity. The principles of metallic corrosion were broadly surveyed with special reference to the controlling factors of immersion and atmospheric corrosion, as well as their application to the prevention of corrosion under service conditions. Extensive measurements were made on various inorganic, polymeric, and organic additives employed in metallic water systems to study their effectiveness in preventing corrosion. For capacitor dielectric systems for which a low conducting dielectric is needed, organic mixtures proved to be the most satisfactory.
