    Description / Table of Contents: Studies on the Behaviour of Ferrous Metals in ElectrodesNo differences in potential could be found between the hexagonal and the cubical forms of Cobalts. A hysteresis loop is formed as a result of the polarisation of Cobalt. This loop disappears with anodic or cathodic pretreatment of Cobalt. The cause of the hystersis loop has been traced back to a mutual action with an oxide surface layer. Iron also behaves in a similar manner; but it was not possible to neutralize the hysteresis loop completely in the case of Nickel. Cold-working of the Iron increases the polarisability of the Iron.
    Notes: Zwischen dem hexagonalen und dem kubischen Kobalt konnten keine Potentialunterschiede gefunden werden. Bei der Polarisation entsteht heim Kobalt eine Hysteresisschleife, die nach anodischer oder kathodischer Vorbehandlung verschwindet. Sie wird auf Wechselwirkung mit einer Oxydhaut zurückgeführt. Ähnlich verhält sich auch das Eisen; beim Nickel gelingt es nicht, die Schleife völlig zu beseitigen. Durch Kaltreckung wird die Polarisierbarkeit des Eisens erhöht.
