This paper briefly describes how to estimate numerically the quantitative uncertainty of potentiodynamic polarization curves obtained from a charge transfer controlled reaction in the case of working electrodes made from C45 steel with specific coatings (WC-Co, WC-Co-Al2O3 and a reference without coatings). The processed dataset was created during a real physicochemical experiment, but potentiostat/galvanostat transformed the dataset of measurements into parameters of Tafel’s lines without uncertainty estimation. The Monte Carlo simulation with resampling (bootstrap approach) was used to estimate confidence intervals of these parameters.Keywords: Uncertainty, quantitative estimation, corrosion potential, corrosion current density, bootstrap
