Adaptive Corrosion Protection System Using Continuous Corrosion Measurement, Parameter Extraction, and Corrective Loop

Figure 1

Polarization curves for iron in a quiescent solution of 0.6 M NaCl open to the air. The anodic and cathodic branches are pointed in the plot. In addition, the slopes of the anodic and cathodic branches along with interpolation of the two branches are also extracted using the dotted line. Based on this extraction, the and values are also determined.
