The inhibition effect of tween-85 on the corrosion of cold rolled steel (CRS) in 1.0 M hydrochloric acid (HCl) was studied by weight loss and potentiodynamic polarization methods. The results show that tween-85 is a good inhibitor in 1.0 M HCl and its maximum inhibition efficiency (IE) is 92% at very low concentration. Its adsorption obeys the Langmuir adsorption isotherm equation. The thermodynamic parameters of adsorption enthalpy (DH 0 ), adsorption free energy (DG 0 ) and adsorption entropy (DS 0 ) were calculated and discussed. Polarization curves show that tween-85 acts as a mixed-type inhibitor in hydrochloric acid. IE values obtained from weight loss and polarization are consistent. The adsorbed film on a CRS surface containing an optimum dose of tween-85 was investigated by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and atomic force microscope (AFM). An inhibitive mechanism is proposed from the viewpoint of adsorption theory.

Springer Science+Business Media, Inc. We have used weight loss measurements, potentiodynamic polarization, and lectrochemical impedance spectroscopy to study the inhibiting effect of N,N-di(polyoxyethylene)-4-dodecylaniline, with different numbers of oxyethylene units, on corrosion of steel in a 1 M hydrochloric acid solution. We have determined that the studied compounds are good corrosion inhibitors. The inhibition efficiency increases with an increase in inhibitor concentration, an increase in the number of oxyethylene units in the chain of the inhibitor, and a decrease in temperature. The inhibiting effect of the studied compounds is due to blocking of the metal surface as a result of adsorption of the oxyethylene units of the inhibitor. The adsorption process is described by the Freundlich isotherm. The indicated compounds act as mixed (mostly anodic) corrosion inhibitors. We calculate some thermodynamic corrosion parameters. Iron and iron alloys are exposed to acids in industrial applications. Acids are used in chemical and electrochemical etching, surface cleaning by acid, including cleaning of oil refinery equipment, oil well acidizing and acid descaling [1]. Inhibitors are used to prevent corrosion of iron or steel or to reduce the corrosion rate in acid media [2]. Corrosion inhibitors have been developed based on organic compounds containing nitrogen, oxygen, sulfur, and multiple bonds, which facilitate adsorption on the surface of the metal [3]. Some organic compounds [4-10] display good corrosion inhibiting properties in acid media. These compounds protect the metal by being adsorbed on its surface. Adsorption is affected by the nature of the metal surface and the charge on it, the type of electrolyte, and the chemical structure of the inhibitor [11].A very effective method for reducing the corrosion rate has been to add high molecular weight organic compounds, acting as surfactants, to the acid media. These compounds are effective inhibitors because their molecules contain long hydrocarbon chains, ensuring high coverage of the metal surface, and also multiple active

The inhibition effect of 2,2'-(((thiobis (4,1 phenylene)) bis(azanylylidene)) bis(methanylyidene)) bis(4-methoxyphenol) (BIS-IMIN) on the corrosion behavior of 304-stainless steel (SS) in 0.5 M HCl solution was studied by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. SEM, FT-IR, 1 H-NMR, 13C-NMR methods used for characterization of BIS-IMIN. Potentiodynamic polarization curves indicated that BIS-IMIN act as mixed type inhibitor. The adsorption of the inhibitor was more suited with the Langmuir adsorption isotherm and kinetic parameters K ads , ∆G ads, E a , ∆H ads, ∆S ads were determined at room temperature. The results showed that BIS-IMIN performed well inhibiting effect for the corrosion of the SS.
