Polarization ResistancePolarizattion Resistant - Simple LPR

We began with a simple LPR (Polarization Resistance) experiment. The results are shown to the right. Analysis of the data within 5 mV of Eoc gave the line shown in red. It corresponds to an Rp value of 687 ohm. Using the default beta values of 120 mV/decade yields a corrosion rate of 5.77 mpy in this electrolyte. This estimate can be refined if better estimates of the beta values are known. More about this shortly!
