“…This result demonstrates the resistance of the coating to corrosive media. Based on observations of corrosion current density, the following equation can be used to calculate the percentage of protection efficiency 34 (%PE). where I corr and I (coating)corr are the corrosion current densities values in uncoated and coated states, respectively.…”

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).

“…XPS has been broadly used in the corrosion protection field in recent years to determine the composition of molecular protective films and the bonding of heteroatoms and metals in corrosion inhibitors. , The XPS studies were conducted on the inhibited brass samples pre-exposed to electrolytic conditions for 24 h to examine the interaction of the studied I Me inhibitor molecules with the brass surface. The analyses were carried out in the binding energy (BE) range of Cu 2p, C 1s, and N 1s peaks.…”

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.

“…Typically, CPE gives a suitable representation for the electrochemical process in place of capacitance. 57 The CPE values can be represented by the following equation: Z CPE = (1/ Y 0 )[j ω ] − n where, Y 0 is CPE (constant), n is an exponent, j is the imaginary value and ω is the angular frequency. The measured C dl values can be represented with the next equation: 58 C dl = ( Y 0 R ct 1− n ) 1/ n where, Y 0 is CPE (constant) and n is the CPE exponent.…”
