“…The quality of fitting to the electrical equivalent circuit was judged by the v 2 values. The obtained v 2 values (0.03898-0.00134) in the table indicate a good fit to the proposed circuit [47][48][49][50][51][52][53][54][55][56]. Percentage inhibition efficiencies values obtained from impedance studies, show the same trend as those obtained from Tafel plot and weight loss measurements.…”

The inhibitory propensity of dry arecanut seed (DAS) extract was tested on aluminum metal in 0.5 M HCl media through weight loss, electrochemical, and probe techniques. Weight loss studies exhibited the anticorrosive effect of DAS extract constituents on the aluminum metal surface, protection efficiency, increased with an increase in the DAS extract concentration and subdued as the contact time lengthened. Inhibitive effect was afforded by adsorption of the DAS extract components which was approximated by proper Langmuir isotherm fit. The activation energy of aluminum corrosion and other thermodynamic functions were determined to corroborate the experimental findings and provide adequate insight into the aluminum corrosion inhibition mechanism. Inhibitive modality of the most potent inhibitor (DAS extract) was interpreted in detail through potentiodynamic polarization technique (Tafel plot). The impedance spectroscopy approach may well be able to foretell the formation of a persistent passive layer at the aluminum-acid interface that impedes the access of corrosive ions to the surface of aluminum. Surface analysis rationalized via atomic force microscopy technique manifested the absence of corrosion products and topographic modifications on the aluminum surface. The amorphous/crystalline nature of the inhibitor (DAS extract constituents) molecules adsorbed onto the aluminum surface was indicated by powder X-ray diffraction technique. Protection efficiency values obtained by all techniques were complied with each other.

“…The usage of inhibitors is an effective way to protect iron against aggressive media [3][4][5][6]. The corrosion behavior of metal can be controlled by many natural extracts and synthetical compounds such as bamboo leaves [7], henna [8,9], coffee [10], Myrtus communis [11], Schiff bases [12][13][14], pyrimidine [15][16][17], thiazole [18][19][20], and imidazoline [21][22][23][24]. Chemical structures of those functional compounds are often related with O, S, N atoms, and multiple bonds which are all electron-rich groups [25,26].…”

“…Inhibition efficiency: The reduced in the corrosion rate by the addition of wood tar extract of Olea europaea subsp. Cuspidata is attributed to rather adsorption of the compounds occur in the extract on the metal surface or the formation of the barrier film separating between the metal surface and the corrosive medium [45][46][47]. Olea europaea subsp.…”

Corrosion is one of the serious problems in industry, specially acidic corrosion which is caused by acidic solutions which are widely used in acid cleaning, acid pickling and acid descaling. Mild steel (MS) is widely used in the the industrial field is vulnerable to be corroded by the acidic solution. In the industrial media, corrosion processes are responsible for the loss of metals. There are various methods to mitigation the degradation or destruction of metal surface. Using inhibitors is one of the most potent methods in control of corrosion is due to its low cost and eases of application and practice. As the concern is focused on the safety of any industrial process in health and environment, the use of organic plants as corrosion inhibitors is in the forefront in the current trend of corrosion inhibition studies. In the last decades the need of novel corrosion inhibitor compounds has become more and more stringent. In this study, the efficiency of the bark of Olea europaea subsp. Cuspidata as corrosion inhibitor for mild steel in 1.0 M sulphuric acid was studied by electrochemical measurements [potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS)]. The results showed that Olea europaea subsp. Cuspidate wood tar oil acts as a potent corrosion inhibitor and the performance of the inhibitor varied with concentrations for mild steel in 1.0 M H2SO4 + 10 % EtOH. The maximum inhibition (%) was 94.97 %, the results were supported by different techniques used. Electrochemical analysis indicated that Olea europaea subsp. Cuspidata wood oil tar extract acts as mixed mainly cathodic inhibitor. Also, surface analysis the scanning electron microscope (SEM) was carried out to determine the corrosion inhibition property of Olea europaea subsp. Cuspidata wood tar oil in (1.0 M H2SO4 + 10 % EtOH) solution. The adsorption of the wood tar extract on mild steel surface followed Langmuir isotherm.
