“…Compared with the blank sample, the content of Fe on surface of Q235 steel remained at a relatively high level of 81.1% after adding the G211 corrosion inhibitor, and the O generation was suppressed to some extent, to 6.0%. Based on the above analysis, the confirmed test results from EIS and PDP demonstrate the successful adsorption of G211 molecules onto the surface of Q235 steel, thereby offering protection against oxidation 47 , 48 .…”

Gemini-type imidazoline quaternary ammonium salt is a new type of environmentally friendly corrosion inhibitor has been widely used in engineering materials. However, most of them are hazardous/toxic compounds derived from petroleum-based products, which did harm to environment. In this work, an environmentally friendly Gemini-shaped imidazoline quaternary ammonium salt corrosion inhibitor (G211) was synthesized using cheap fatty acid recycled from dimer acid industry as feedstock. The corrosion inhibition effects of G211 on Q235 steel in 1 M HCl solution were investigated through weight loss experiments, potential polarization curves, and alternating current impedance spectroscopy experiments. The results show that the inhibition rate of G211 as a mixed-type inhibitor is up to 94.4% and the concentration drop as low as 500 ppm at 25 ℃. The adsorption of G211 on Q235 surface follows Langmuir adsorption isothermal curve. The chemical composition of the Q235 steel surface was analyzed through scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Furthermore, the possible corrosion inhibition mechanism of G211 on the surface of Q235 steel is proposed. This article not only presents an outstanding solution for safeguarding Q235 steel against corrosion but also introduces a feasible method for high-value utilization of monomer acid (MA).

“…The molecular dynamics simulation findings showed that the corrosion inhibitor molecules replaced the solvent water or any other ions preadsorbed on the metal surface during the adsorption process and protecting the metal against corrosion. As a cheap natural biomolecule, glucose has proven significant corrosion inhibitor for various metals in the acidic and basic media [12]. The two thiocarbohydrazide-modified glucose derivatives (TBTD-1 and TBTD-2) were synthesized using N-glycosylic linkage.…”

Metal corrosion constitutes degradation of metals in the presence of favorable corrosive atmosphere. It worsens metal quality. The prevention of metal corrosion is so significant to save metals for their better utility. Corrosion inhibitors are widely used for the mitigation of metal corrosion. Small organic molecules as corrosion inhibitors are showed prominent corrosion inhibitive property because of their unique electron donating capacity to the metal orbitals. The bonding occurred between organic molecules and metals are main aspect to retard the corrosive environment toward metal.
