Net polarization curves

Fig. 5.9 Schematic representation of relative positions of the net polarization curves to the individual curves for anodic metal polarization and cathodic hydrogen and water polarization, pH = 1. Curve M, anodic polarization for metal (e.g., Fe-18% Cr) curve H, cathodic polarization for H+ curve W, cathodic polarization for H20 curve SC, sum of cathodic polarization for H+ and H20 curve N, net curve for anodic and cathodic polarization. Note Curve N coincides with curve M above-100 mV and with curve H below-350 mV.

Fig. 5.14 Net polarization curves, N, associated with the individual anodic and cathodic polarization curves. pH = IPo, = 0.2 atm. Curve M, anodic polarization curve for metal curve H, cathodic polarization cu rve for H+ curve W, cathodic polarization curve for H20 curve O, cathodic polarization curve for 02 curves N, net anodic and cathodic polarization curves.

Fig. 5.17 Net polarization curves, N, resulting from the metal anodic curve, M, and the sum cathodic curve, SC, for the oxygen-reduction and hydrogen-ion-reduction curves. Curves M and SC are from Fig. 5.16. pH = 1. PQ = 0.05 atm...
