“…15,27 This protocol would lead to significant improvements in material performance, for instance, in the wettability, 27 zeta potential 25 and corrosion inhibition efficiency. 28 On the other hand, pretreatments via diazonium chemistry enable the pristine inert surfaces to undergo further incorporation of polymers, 29–31 proteins 26,32 or ligands for certain metal ions, 33–35 equipping the original materials with novel properties. In general, subsequent modifications are carried out by graft-onto, 29,36 graft-from 30,31 and graft-through 37 strategies.…”

“…Researchers have investigated the corrosion inhibition property of sodium lignosulfonate in HCl, using three different independent monitoring techniques, which are weight-loss measurements, electrical conductance, and potentiodynamic polarization [ 10 , 11 ]. Many researchers have studied the corrosion inhibition of steel and other metals in various environments, including HCl [ 4 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. The mechanism of inhibition depends on many factors, such as the metal type, medium type and concentration, nature of the inhibitor, and temperature [ 23 ].…”

The aim of this research is to study the anticorrosive behavior of a coating consisting of modified montmorillonite nanoclay as an inorganic green inhibitor. The anticorrosion protection for mild steel in 1.0 M HCl solution is studied via weight loss, electrochemical methods, SEM, and XRD. The results proved that montmorillonite nanoclay acts as a good inhibitor with a mixed-type character for steel in an acidic solution. Both anodic and cathodic processes on the metal surface are slowed down. There is a clear direct correlation between the added amount of montmorillonite nanoclay and the inhibition efficiency, reaching a value of 75%. The inhibition mechanism involves the adsorption of the montmorillonite nanoclay onto the metal surface. Weight loss experiments are carried out with steel samples in 1.0 M HCl solution at room temperature, and the same trend of inhibition is produced. SEM was used to image the surface at the different stages of the corrosion inhibition process, and also to examine the starting nanoclay and steel. XRD was used to characterize the nanoparticle structure of the coating. Montmorillonite nanoclay is an environmentally friendly material that improved the corrosion resistance of mild steel in an acidic medium.

“…In recent decades, there has been a strident interest in finding new inhibitors for corrosion prevention [1][2][3][4][5]. This search has been driven by a desire to find more environmentally friendly inhibitors to replace chemicals that represent environmental and health risks [6][7][8][9][10].…”

The protection of ferrous metals in acidic environments is important in many industries. Extending the pH range of organic inhibitors to low pH has been achieved with the addition of iodide ions, which facilitate adsorption. It was of interest to see whether similar outcomes could be achieved with inorganic inhibitors. To this end, this paper examines the influence of potassium iodide addition on the level of corrosion protection provided by Ce(NO3)3 in 3.5% NaCl electrolytes over a pH range of 2.5 to 8. Potentiodynamic polarization was used to assess percentage inhibitor efficiency (IE%), and scanning electron microscopy, energy dispersive X-ray spectrometry, and X-ray photoelectron spectroscopy were used to characterize the corrosion product. It was found that KI alone provided only poor corrosion inhibition except at pH 2.5, where nearly 85IE% was achieved. Its addition to the cerium electrolytes was generally in excess of 90% and over 97% for the optimum concentration. The addition of KI seemed to change the mechanism of formation of corrosion products from predominantly Fe2O3 to a mixture of FeOOH, Fe3O4, and Fe2O3, which were more adherent. Corrosion protection was extended to pH 4, but under the conditions explored here, no additional protection was evident at pH 2.5.
