“…The value of the I corr decreases as the inhibitor concentration increases, meaning that IE EFM increases, implying that the GS inhibits corrosion via adsorption on the brass alloy surface, resulting in the creation of a protective barrier layer over the surface . The values of β c and β a are changed significantly with the presence of GS compounds, confirming that the cathodic hydrogen evolution and anodic copper and zinc dissolution were considerably diminished in the presence of these compounds.…”

For a variety of applications, the brass alloy has been utilized to replace titanium tubes in heat exchangers. Copper alloys’ high corrosion rate during the acid cleaning procedure remains a significant concern. To inhibit the corrosion of brass alloys, we prepared two novel gemini surfactants (GSs), N 1 , N 3 -dibenzyl- N 1 , N 1 , N 3 , N 3 -tetramethylpropane-1,3-diaminium tetrafluoroborate (I H) and N 1 , N 1 , N 3 , N 3 -tetramethyl- N 1 , N 3 -bis (4-methyl benzyl) propane-1,3-diaminium tetrafluoroborate (I Me), and they were characterized using Fourier transform infrared spectroscopy and 1 H nuclear magnetic resonance spectroscopy. Their inhibition performance against corrosion of brass alloys in 1 M HCl was studied using electrochemical techniques including potentiodynamic polarization (PP), electrochemical impedance spectroscopy, and electrochemical frequency modulation. The inhibition effect of the synthesized compounds was high, and it increased as the inhibitor’s concentration was increased. The maximum level of inhibition efficiency was achieved at an inhibitor concentration of 100 ppm, reaching 96.42% according to PP measurements. From Langmuir data, the mechanisms of adsorption of the two GSs on the surface of copper was found to be physisorption and chemisorption adsorption. X-ray photoelectron spectroscopy and scanning electron microscopy show that the addition of the two compounds lowers the dissolution of brass ions in the corrosive solution and forms a protective layer on the surface of the brass.

“…16 shows that the HOMO is much more localized toward them. 83–87 From the values listed in Table 11, the E HOMO values are equal to −8.8862, −8.8451 and −8.6592 eV using Semi-empirical PM6, −8.1895, −7.8587 and −7.7710 eV using HF-631G, and −5.9715, −5.8948 and −5.6592 eV using DFT/B3LYP/6-311+G for PhODB , BODB and DODB , respectively. From the abovementioned E HOMO results, DODB has the highest E HOMO values and so it is has the greatest ability to donate electrons to the MS surface, leading to the formation a protective layer on its surface which is stronger than for BODB or PhODB .…”

“…16 shows that the HOMO is much more localized toward them. [83][84][85][86][87] From the values listed in hardness (h) are two chemical parameters which are related to each other. Chemical hardness prevents chemical molecules from deforming, and global hardness is negatively correlated with soness, so the highest soness compounds have the lowest hardness values.…”

This study uses nickel nanoparticles coated on the nickel–chromium (Ni–Cr) alloy by the electrodeposition technique to protect the alloy against corrosion. An open-circuit potential and potentiodynamic and linear polarization resistance in a 1 M H 2 SO 4 solution saturated with carbon dioxide were used to study the anticorrosion performance of nanoparticle coatings. When coated with nanomaterials, the corrosion rate of Ni–Cr alloy was lower than when it was bare, and the potential for corrosion increased from −0.433 V for uncoated Ni–Cr alloy to −0.103 V when the electrodes were exposed to saturated calomel. Electrochemical experiments show that nickel-coated Ni–Cr alloy corrosion in sulfuric acid media has high protective characteristics, with an efficiency of 83.69% at 0.165 mA/cm 2 current density when pH = 1 is used. As demonstrated by the results of this research, the nickel–chromium alloy can be protected from corrosion in acidic media by a low-acidity bath coating layer. Surface morphologies have shown that coatings at different acidic scales may be able to resist an acid attack because of their excellent adherence to the nickel–chromium alloy surface. Measures for determining and studying the composition of the alloy surface’s protective covering were improved using X-ray diffraction (XRD).
