In this chapter, we tried to create a link between repassivation kinetics, electrochemical noise and SCC. To measure an electrochemical noise signal that can be related to a cracking event, an anodic current from a bare metal surface is required. This anodic current does not necessarily have to be the rate determining step in the SCC process, but it has to be related to a cracking event. This anodic current causes a potential drop in the electrolyte solution that can be picked up by a suitable electrode.
