Improved Tafel-Based Potentiostatic Approach for Corrosion Rate Monitoring of Reinforcing Steel

Abstract Potential step voltammetry (PSV) was introduced in earlier works as an advantageous alternative to traditional methods for measuring corrosion rate reinforced concrete. The present study aims improve PSV maximize its applicability monitoring, that is, beyond the narrowly-defined steel–concrete systems which initially validated. It therefore identified necessary address most suitable pulse amplitudes accurately obtain Tafel lines and, therefore, steel-mortar with well-differentiated ohmic drop. findings were compared reference methods, i.e. intersection and linear polarization resistance. As a novelty, we propose procedure reliability of PSV-determined lines, is based on three protocols (P1, P2 P3). P1 consists specific sequence characterize morphology curve without disturbing system. two short pulses determining drop compensation factor. Finally, P3 simple calculation adjust (∆V) system assessed, thus obviating need preset values ensuring accurate results. proposed intended view consolidation reliable tool unsupervised monitoring real structures.
