Kathodische Korrosion von Blei im Erdboden

Cathodic corrosion of lead in the soil Cathodic corrosion of lead in the soil can be expected in exceptional cases only. The corrosion found on a particular lead cable could be simulated in the laboratory. It could be confirmed, that — probably by decomposition of primary lead hydride — metallic lead is deposited below layers of Ca and Mg compounds already at potentials below ?1,7 V. A special switching method was developed to account for breakthrough polarisation.
