Determination of corrosion rate of molybdenum, rhenium and their alloys in sodium chloride solution by the method of Tafel extrapolation

Based on the measured voltammograms, the corrosion potentials and corrosion current densities of Mo, Re, and several their alloys in the NaCl solutions were determined by the method of Tafel extrapolation. The dependences of E corr and i corr on the alloy composition, including the corresponding val...

Description
Summary:Based on the measured voltammograms, the corrosion potentials and corrosion current densities of Mo, Re, and several their alloys in the NaCl solutions were determined by the method of Tafel extrapolation. The dependences of E corr and i corr on the alloy composition, including the corresponding values for the metals (alloy components), were plotted. The obtained values of i corr and the corrosion rates in the linear units were compared with the literature data.
