Inhibition of Copper Pitting Corrosion in Aggressive Potable Waters

Figure 7

Chlorine demand (dark shading) and computed average pit propagation rates (light shading) based on 𝐸_pit=325 mV (versus Ag-AgCl). No propagation rate is shown for tests in which 𝐸_pit was not observed. Conditions are grouped by respective changes to the control water quality (^ANOM, ^Bozonated NOM, ^Csodium acetate/d-glucose), and the control tests are shown with hash marks in each grouping. S and L indicate small- and large-scale tests, respectively.
