“…The values of the corrosion current density (i corr ) for N80 mild steel corrosion reaction in the absence and presence of the inhibitor were determined graphically by extrapolating the linear Tafel segment of the cathodic curves to the E corr as described previously for non-Tafel dependence curves [17,25,32] and presented in Table 2. Also shown in Table 2 is the inhibition efficiency of CQI for the CO 2 corrosion of N80 mild steel calculated from the following equation:…”

“…R s is the solution resistance, and R ct , the charge transfer resistance is attributed to the corrosion reaction at the electrode/solution interface [33]. R f represents the resistance of the film formed on the copper surface, and W indicates the Warburg impedance.…”

“…Therefore, due to absence of linearity in anodic branch, accurate evaluation of the anodic Tafel slope by Tafel extrapolation of the anodic branch is impossible [52][53][54]. Accordingly, the electrochemical parameters of corrosion processes could be determined by Tafel extrapolation of the cathodic curve to the cathodic linear region back to the corrosion potential [55,56]. But it has been shown that in the Tafel extrapolation method, use of both the anodic and cathodic Tafel regions is undoubtedly preferred over the use of only one Tafel region [57].…”
