Appearance・Structure

Atmospheric corrosion systems under electrolyte immersion and a water film are represented by the equivalent circuit. Z is the impedance, Rp is the polarization resistance (∝ corrosion resistance), Cdl is the electric double layer capacitance, and Rs is the solution resistance. Since it can be approximated that Z ≒ Rs when ω→∞, and Z ≒ Rs + Rp when ω→0, the solution resistance Rs can be measured from the high frequency side, and the polarization resistance Rp can be calculated by subtracting value on the high frequency side from the value on the low frequency side. The inverse of the polarization resistance is correlated with the corrosion rate. Therefore, it is possible to grasp the change in the corrosion rate over time.
