“…174,175 Based on the thermodynamic calculations, both research groups suggested physisorption as the possible adsorption mechanism for the respective honey types studied. 174,175 Abdallah et al 176 boiled animal connective tissue for a long time and tested the obtained glue as a corrosion inhibitor for aluminium as well as AA6063 and 20556 (92.47% aluminium) aluminium alloys in 0.1 M NaOH solution at 30 C. The inhibition effectiveness decreased with increasing Si content following the order aluminium > AA6063 alloy > 20556 alloy. An increase in temperature resulted in a decrease in inhibition effectiveness.…”

“…3. The decrease in the two Tafel slopes with the increase in the extract concentration shows that Mentha pulegium essential oil is a mixed inhibitor, acting on both anodic and cathodic reactions by the formation of a protective film onto the aluminum surface [26][27]. The sharp decrease of the corrosion current density from 178.21 µA / cm 2 to 10.39 µA / cm 2 reflects that Mentha pulegium essential oil is a good inhibitor, reaching a maximum inhibition of 94.16%, at a concentration of 800 ppm.…”

The corrosion inhibition of aluminum, in 0.1 M Na2CO3, by Mentha pulegium essential oil, was studied using both polarization and impedance methods. The results show that Mentha pulegium is an effective inhibitor, providing an inhibition rate of 94.16 %, with a concentration of 800 ppm. The polarization study shows that the Mentha pulegium essential oil acted as a mixed inhibitor in 0.1 M Na2CO3. The activation energy calculation has proved that the inhibitor molecules adsorbed onto the aluminum surface, according to the physisorption mechanism.

“…In one hand, the extensive use of mild steel in industries including oil production, oil refining, power stations and civil engineering structures has been widespread due to relatively low cost, high strength and availability [2]. On the other hand, the light weight of aluminum alloys, their low density and high thermal and electrical conductivity make them widely used in many industrial applications such as automotive and aircraft industries [3]. However, if the metal suffers from corrosion problem, the previous properties and qualities could be useless for industrials.…”

Many industries worldwide use steel and aluminum as the principal raw material. In one hand, thanks to its lightweight and durability, aluminum is widely used in all sectors of the transportation industry-land, sea, and air. In the other hand, production process of steel equipment's is generally less expensive than others and its recyclability can be infinite. For this reason, it is one of the most used metals. After the production process, the finished metallic product needs a pickling process using aggressive acids such as hydrochloric acid. Consequently, aluminum and steel products are exposed to the corrosion phenomenon. For this reason, the present work investigates the anticorrosion effect of Lavandula maroccana ethanol extract on both aluminum and mild steel corrosion in 1M HCl solution. In fact, plant extracts inhibitors are replacing synthesized compounds that are usually environmentally toxic. Electrochemical measurements are the main data used to analyze the inhibition effect of LM inhibitor using the potentiostat device (PGZ100). Electrochemical impedance spectroscopy technique (EIS) showed an increase in the charge transfer resistance of mild steel specimen. The high inhibition efficiency is 89% for mild steel in 1M HCl using 400ppm of LM extract. For aluminum alloy used in this study, the high inhibition efficiency reached 68%. Scanning electron microscopy (SEM) and UV-visible surface analysis were also applied to investigate the effect of LM extract inhibitor on aluminum alloy and mild steel specimen.
