Synergistic inhibition effect of potassium iodide and novel Schiff bases on X65 steel corrosion in 0.5M H2SO4

Synergistic corrosion inhibition of environment-friendly inhibitors on the corrosion of carbon steel in soft water

“…1 and Table 6 show that the composite inhibitors cause a remarkable decrease in the corrosion rate, shifting both anodic and cathodic Tafel curves to lower current densities. The more pronounced effect of inhibitors on the anodic slopes than on the cathodic Tafel slopes confirmed that the anodic process of carbon steel corrosion in the tested soft water was effectively retarded by the addition of composite inhibitors [2] and [7]. The performances shown in Fig.…”

“…Electrochemical measurements by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarisation techniques are commonly used to identify the inhibitor type, model the corrosion and film-forming processes on the metal/solution interface, and calculate the corrosion inhibition efficiency of inhibitors based on specific parameters [2], [7], [9], [43], [44], [45] and [46].…”

“…These systems are known to cause relatively high levels of metal corrosion [1], and enable the release of iron corrosion by-products into potable water [2], [3] and [4]. Carbon and low-alloy steels are the major construction materials extensively used in water distribution, petroleum, power production, as well as chemical and electrochemical industries [5], [6] and [7]. However, iron-based alloys are inevitably subject to corrosion, especially pitting corrosion in neutral or acidic solutions containing aggressive anions [8].…”

Evaluation of anticorrosion properties of Chrysophyllum albidum leaves extract for mild steel protection in acidic media

“…It should be noted that the cathodic polarization curves give rise to almost parallel Tafel lines, which indicates that the addition of CA extract did not modify the mechanism of the hydrogen evolution reaction process. That is to say, the presence of CA extract can inhibit the corrosion reaction only by blocking the reaction sites without affecting the actual reaction mechanism [39][40][41]. However, the increase of the anodic Tafel slopes in the presence of the additive suggests that CA extract can affect the kinetics of the anodic process.…”

Synergistic effect of polyethylene glycols and rare earth Ce4+ on the corrosion inhibition of carbon steel in sulfuric acid solution: electrochemical, computational, and surface morphology studies

“…Synergism of corrosion inhibitors is due to either interaction between the inhibitor and one of the ions present in the aggressive solution or interaction between components of the inhibitor composition [13]. Use of such synergistic inhibition effects (synergism) is an effective approach to improve the performance of inhibitors, decrease the amount used, and diversify their applications in acidic media [14]. In literature studies, synergism between organic inhibitors and halide ions against corrosion of metal in acidic solution has been investigated [15][16][17][18].…”
