“…In addition, the positive sign of the enthalpy of activation illustrates the endothermic nature of the aluminum corrosion process. [34] Furthermore, as indicated in Table 2, the ΔS act value in the absence of the additive was −218.9 J mol −1 K −1 , while it became less negative (i.e., −165.8 J mol −1 K −1 ) with 500 ppm casein. This variation in ΔS act further confirms the adsorption of the inhibitor molecules on the surface of aluminum, which replaced the water molecules already present in the vicinity of the specimens.…”

In this study, the efficiency of casein in inhibiting the corrosion of aluminum in 0.1 M HCl was evaluated. Based on the weight loss data, increasing the amount of casein in the electrolyte from 50 to 500 ppm at 298 K decreased the corrosion rate of aluminum, for instance, from 2.53 to 0.58 g m−2 h−1. It was also demonstrated that with casein, the activation energy of the corrosion phenomenon increased (e.g., from 6.52 kJ/mol without casein to 27.54 kJ/mol with 500 ppm casein). The electrochemical polarization studies illustrated that in the presence of 500 ppm casein, the corrosion current density remarkably decreased from 63.09 to 6.1 µA/cm2. This was compatible with the increase in the charge transfer resistance recorded by electrochemical impedance spectroscopy. Furthermore, the X‐ray photoelectron spectroscopy and atomic force microscopy techniques confirmed the adsorption of casein on the working electrodes, which caused an enhancement in the surface quality of the specimens.

“…As a result, numerous treatments and investigations are required to mitigate aluminium corrosion to some level [5]. To address this issue, an efficient and practical approach to avoiding metal corrosion has usually been employed, i.e., the use of inhibitors [6,7]. Corrosion inhibitors are chemical compounds that, when introduced to a corrosive medium at low quantities, decrease or prevent metal corrosion [8][9][10].…”

“…In industries, adding inhibitors is particularly prevalent since it can be done without pausing or affecting the process. Researchers are currently looking for a safe inhibitor that has the best effect on corrosion prevention [5][6][7]. The success of such large-scale inhibitor applications is dependent on slowing down the corrosion process.…”

The new Schiff base, 2,2'-((1Z,1'Z)-(((propane-1,3-diylbis(oxy))bis(2,1-phenylene))bis(methanylylidene))bis(azanylylidene))diethanol, was investigated as a corrosion inhibitor of aluminium in 1 M HCl. Polarization and electrochemical impedance measurements were used for this purpose. Polarization curves showed that the compound is a mixed-type corrosion inhibitor. Also, the results showed an increase in inhibition efficiency as the concentration of the compound increased. The maximum corrosion inhibition efficiency of approximately 81 % was reached at the concentration of 2 mg/L of the inhibitor. The results of the density functional theory method were consistent with the experimental results. The surface morphology of the samples was examined under atomic force microscopy.
