“…Because of this, researchers have been focused in investigating the inhibitory properties of easily available and low cost natural products that, in addition, are not harmful to health and to the environment, which are generally denominated green inhibitors 6 . In the literature, several studies are available on the efficiency of leaves or peel extracts as corrosion inhibitors for carbon steel in acidic solutions (generally electrolyte prepared using 37% m/v HCl), like aqueous extracts of mango and orange peel 2 , and alcoholic extracts of Astemisia Mesatlantica oil 7 , Roselle 8 , Eruca sativa 9 , Saccocalyx satureioides 10 , Argemone mexicana 6 , Chrysophyllum albidum 11 , Agavoideae 12 , Tiliacora accuminata 13 , Pimenta dioica 14 , Ilex paraguariensis 15 , Aniba rosa eodora 16 , Ruta chalepensis 17 .…”

The inhibition effect of castor bark powder obtained from Ricinus communis on AISI 1020 carbon steel in acidic media (HCl 0.5 mol.L -1 ) has been studied by electrochemical impedance spectroscopy (EIS), polarization curves, scanning vibrating electrode technique (SVET) and weight loss measurements. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were employed as characterization techniques. The EIS and gravimetric results showed that the inhibitory efficiency increases with inhibitor concentration achieving 83%. Polarization curves indicated that the castor bark powder acts as mixed inhibitor. The adsorption of the powder components on the metal surface follows the Langmuir isotherm. The FTIR analyses indicate the presence of C, N and O heteroatoms, incorporated in functional groups mainly related to the presence of carboxylic acids as ricinoleic acid, which could be responsible for the inhibitory properties of the powder. SEM analyses showed that the corrosion process was retarded in the presence of inhibitor in the electrolyte, which was confirmed by SVET measurements. Therefore, the results indicate that castor bark powder has potential to be a corrosion inhibitor for carbon steel in acidic media.

“…As shown in Table 2, the corrosion current density ( corr ) values decrease with increasing inhibitors concentrations as well as increase of inhibition efficiency, indicating that the adsorption of the inhibitors molecules on the surface of steel is impeded by blocking the reaction sites [25,26]. It can be seen that the inhibition efficiency varies from 84.49% to 95.11% and shows the following order of inhibition: Camphor thiosemicarbazone (5), Carvone thiosemicarbazone (6), and Pulegone thiosemicarbazone (7), respectively, for the concentration of 5 mmol/L.…”

We have studied the inhibitory effect of some Monoterpenic Thiosemicarbazones on steel corrosion in 1 M HCl solution. The potentiodynamic polarization and electrochemical impedance spectroscopy were used. The Monoterpenic Thiosemicarbazones have inhibited significantly the dissolution of steel. The inhibition efficiency increased with increasing inhibitor concentration and also with the increase in temperature (293-323 K). Furthermore, the results obtained revealed that the adsorption of inhibitor on steel surface obeys Langmuir adsorption model and the thermodynamic parameters such as enthalpy and activation energy were determined. The scanning electron microscopy combined with dispersive X-ray spectroscopy examinations were used to see the shape of the surface morphology and to determine the elemental composition. Scanning electron microscope (SEM) images show that the surface damage decreases when the inhibitor is added. The quantum chemical calculations using density functional theory (DFT) were performed in order to provide some insights into the electronic density distribution as well as the nature of inhibitorsteel interaction.

Brass is widely used as turbine material for cooling system for marine propellers. However, it is vulnerable to corrosion by contact of air or aqueous chloride solution. The essential oil of Myrtus communis (MO) was tested as a brass corrosion inhibitor (Cu70-Zn30) immersed in the 3% NaCl solution, using a polarization technique and electrochemical impedance spectroscopy. The effect of MO concentration, temperature and immersion time was studied to evaluate the action of the inhibitor. The results showed that the protection efficiency was enhanced with the increasing of MO concentration, and the potentiodynamic polarization experiment showed that MO acts essentially as a cathodic inhibitor. In addition, experiments have shown that MO inhibition efficiency decreases with increasing immersion time and temperature. The film adsorbed on the brass surface containing MO was confirmed by the results of the Scanning Electron Microscope (SEM) and the Energy Dispersive X-ray (EDX). The overall results affirmed the potential use of MO as inhibitor agent of brass corrosion in the 3% NaCl solution.
