    Abstract

    Laboratory experimental techniques are described for the study of galvanic corrosion between carbon black filled polyethylene cathode and galvanized steel, stainless steel, copper, tinned copper, and lead anodes. The environmental variables include 0.001N to 1.0N sodium chloride and sodium sulfate solutions in air-containing and deaerated conditions. Experiments in 1N sodium chloride, adjusted with hydrochloric acid or sodium hydroxide, show the behavior of the above galvanic cells in the 2.5 to 10.5 pH range. Corrosion current densities derived from polarization diagrams for the galvanic couples are presented to demonstrate the effectiveness of the experimental technique.
