Abstract:
Potentiostatic anodic polarization is an important technique used in evaluating the performance of anodic corrosion inhibitors. A description of the technique, an explanation of the curves generated, and examples of its application to steel in concrete-type environments are given. Also presented are polarization data which confirm the effectiveness of calcium nitrate as a corrosion inhibitor for steel in concrete over a broad range of chloride concentrations and Cl-/NOz- ratios.*
