摘要

Exploring the depassivation process of reinforcing steel in concrete and the chloride threshold level (CTL) is a major corrosion research challenge. The depassivation process is influenced by a magnitude of parameters. One of them is the steel potential in combination with its distribution, its deviations and the resulting differences and polarization states. For certain electrochemical test methods sometimes an external polarization is applied, but the influence on naturally ongoing processes like the depassivation of the steel is not totally explored. Previous investigations in the literature lead to contrary conclusions.
