“…The shape of the Nyquist plot for bare copper electrode is different from those of AHA-modified electrodes. The latter ones are composed of a high-frequency imperfect semicircle and a straight line seen as Warburg impedance in the low frequency [30].…”

“…The comparison of this work with other inhibitors, such as 4-amino-antipyrine (AAP) [30], as well as 2,5-dimercapto-1,3,4-thiadiazole (DMTD) [40], bis-(1-benzotriazolymethylene)-(2,5-thiadiazoly)-disulfide (BBTD) [5], purine (PU) [41], 5-Mercapto-3-phenyl-1,3,4-thiadiazole-2-thione potassium (MPTT) [42], is listed in Table 6. By contrast, it can be seen that the AHA is an effective corrosion inhibitor for copper in 3 wt% NaCl.…”

Corrosion inhibition effect of AHA film formed on the copper surface by self-assembled monolayers technique was estimated in 3 wt% NaCl solution by electrochemical impedance spectroscopy and polarization methods. Polarization data indicated that AHA was an anodic inhibitor. The maximum inhibition efficiency reached 93.5% in the case of assembly 3 h in 10 mM AHA solution. The adsorption of AHA on the copper surface fits Langmuir adsorption isotherm. Surface-enhanced Raman scattering together with quantum chemical studies demonstrated that N-O and C=O groups were attached to the copper surface, predicting the feasible adsorption centers and confirming the relationship between the molecular structures of AHA and its inhibition property.

“…Also Table 9 shows that, on increasing the temperature the corrosion current Icorr is increased, while IE% increased with increasing the temperature. Through these circumstances 5BID can be described as a mixed-type inhibitor, its inhibition is caused by adsorption, and the inhibition effect results from the reduction of the reaction area on the surface of the carbon steel [47]. Figure 4, shows the curves of Tafel anodic and cathodic polarization for the corrosion of carbon steel in a solutions of 3.5% NaCl, with and without the addition of 5BID at various concentrations.…”

Abstract:The inhibiting efficiency of synthesis a new derivative of 5-bromo isatin it is N-[(hexahydrodiazepine -3,7-dione-1-yl) aceto]-3-(tolylimino)-5-bromo-2-oxo-indole] (5BID) towards carbon steel corrosion have been investigated in three media (vacuum, DMSO, and H 2 O) using PM3 and DFT quantum mechanical calculations of (B3LYP) with a 6-311++G (2d, 2p) by using Gaussian-09 program. The calculated physical properties and quantum chemical parameters correlated to the inhibition efficiency all are studied and discussed at the equilibrium geometry in the three media, the result show that the studied derivativ could be absorbed on carbon steel surface with very good inhibition efficiency by offering electrons from the rich hetero-atoms nitrogen, oxygen, sulfur, and electrons of isatin ring to the unoccupied d-orbitals of Fe metal forming anti-bonding orbital-feedback bonds and also experimental studies of carbon steel corrosion inhibition in 3.5% NaCl solution by (5BID) was account using potentiodynamic polarization, SEM (Scanning Electron Microscopy) and AFM (Atomic Force Microscopy) and EDS (Energy Dispersive Spectroscopy) measurements.
