Chemical, Electrochemical and Quantum Chemical Studies for Famotidine Drug as a Safe Corrosion Inhibitor for α-Brass in HCl Solution

Electrochemical and quantum chemical studies on the corrosion inhibition of 1037 carbon steel by different types of surfactants

“…The values of are larger than the analogous values of Δ H *, indicating that the corrosion process must involve a gaseous reaction, simply the hydrogen evolution reaction, associated with a decrease in the total reaction volume”. These data verified the known thermodynamic relation among and Δ H * 39 which is as follows eqn (6) : …”

Green inhibitor of carbon steel corrosion in 1 M hydrochloric acid:Eruca sativaseed extract (experimental and theoretical studies)

“…The chi square value was utilised to assess the same circuit fitting's quality. 115 Table 5 shows that the chi square values obtained (0.000245 to 0.000404) indicate a decent match to the proposed circuit. The Nyquist and Bode plots of the studied systems are shown in Fig.…”

Aizoon Extract As a Novel Eco-friendly Corrosion Inhibitor For Stainless Steel430 in HCl Solution

“…Also, the peak related to C-H shifted from 2918 to 2921 cm -1 . Moreover, the peak that belongs to the carbonyl group for pure Aizoon extract was in 1715 and shifted to 1730 cm -1 when examined over SS430 surface after immersion in HCl-Aizoon mixture accompanied with a decrease in its intensity which supports the possibility of adsorption of Aizoon compounds on SS430 surface [32,33]. In other words, the shift in peaks can be assigned to the interaction between extract molecules and active sites on metal surface.…”
