“…Inhibitors are generally used in these processes to control the metal dissolution. Most well-known acid inhibitors for steel corrosion are organic compounds containing hetero atoms [2][3][4][5][6][7][8][9][10][11][12]. To be effective, an inhibitor must also displace water from the metal surface, interact with anodic or cathodic reaction sites to retard the oxidation and reduction corrosion reaction, and prevent transport ion of water and corrosion active species on the surface [13].…”

The effect of three compounds of non ionic surfactants, namely, ethoxylated fatty amines with different number of ethylene oxide unit on the corrosion of carbon steel (Type L52) in 1 M HCl has been studied using weight loss and galvanostatic polarization measurements. The percentage inhibition efficiency was found to increase with increasing concentration of inhibitor, number of ethylene oxide units and with decreasing temperature. The inhibitive effect of these compounds was interpreted in view of their adsorption on the steel surface, through their ethoxy groups. The adsorption of these compounds was found to obey the Langmuir isotherm. The effect of temperature on the rate of corrosion in the absence and presence of these compounds was also studied. Some activated thermodynamic parameters were calculated.

The inhibition effect of some Schiff base compounds toward the corrosion of 1018 carbon steel in hydrochloric acid solution was studied using weight loss, galvanostatic polarization, and electrochemical impedance spectroscopy measurements. The percentage inhibition efficiency increased with increasing inhibitor concentration and with decreasing temperature. The polarization measurements indicated that the inhibitors are of mixed type and inhibit corrosion by adsorption on the steel surface. The adsorption process is described by the Freundlich adsorption isotherm. The activation energy and some activation thermodynamic parameters were calculated and explained. From the impedance data it is found that the corrosion of carbon steel is controlled by the charge transfer process at all concentrations of inhibitors.

“…The use of inhibitors is one of the most practical methods for protection against corrosion especially in acid solutions to prevent metal dissolution and acid consumption [1]. Most well known acid inhibitors for steel corrosion are organic compounds containing [2][3][4][5][6][7][8][9][10]. It has been observed that most of the organic inhibitors act by adsorption on the metal surface [11].…”

The effect of 2-amino-4,6-dihydroxy pyrimidine (ADHP) on the corrosion of carbon steel in 1 M HCl has been studied using weight loss and galvanostatic polarization measurements. The percentage inhibition efficiency was found to increase with increasing concentration of the inhibitor, and with decreasing temperature. The inhibitive effect of these compounds was explained on the basis of the formation of an insoluble complex adsorbed on the metal surface. The adsorption process follows Langmuir adsorption isotherm. The effect of temperature on the rate of the corrosion in the absence and presence of these compounds was also, studied. The activated thermodynamic parameters were calculated and explained.
