“…The higher inhibition efficiency of L3Q and H3Q was due to the presence of pi-electrons, quaternary nitrogen atom, and the larger molecular size which ensures greater coverage of the metallic surface [29,30]. L3Q and H3Q form complexes with the ions on the metal surface.…”

Linear and heavy alkyl benzene (HAB) were sulfonated with fuming sulfuric acid (oleum) and the sulfonated products were esterified with tri and poly ethanolamine (d ¼ 4 and 6). The prepared three esters from each series were quaternized with n-butyl bromide. The resulted six quaternized ester of linear and HAB sulfonate were named as (L1Q, L2Q, L3Q, H1Q, H2Q, and H3Q). The surface and thermodynamic properties of these compounds have been investigated. From the data obtained, it was found that surface tension and surface active properties for the HAB derivatives were better than which obtained from linear alkyl benzene (LAB) derivatives. From the results obtained from the surface activity, the best performance compound from each group was selected to study the corrosion inhibition efficiency of them relative to the surface activity. The obtained results show that the LAB derivative L3Q exhibited inhibition efficiency (93.1%) at 1000 ppm but H3Q exhibited (97%) at 600 ppm. The diversity of the resulted data obtained was discussed in the light of chemical structure of the alkyl benzene sulfonate.

“…To counteract this, corrosion inhibitors must be injected continuously through the system [2]. The inhibition of steel corrosion in acidic media using surface active agents (surfactants) has been achieved by many workers [3][4][5][6][7][8][9][10][11][12][13]. The present work aimed to study the adsorption properties and the inhibitive effects of environmental friendly ethoxylated fatty alkyl amine surfactants on the corrosion rate of carbon steel in 1 M hydrochloric acid solution by both chemical and electrochemical techniques.…”

Four novel non-ionic ethoxylated fatty alkyl amine surfactants (I-IV) were synthesised and investigated as corrosion inhibitors of carbon steel in 1 M hydrochloric acid solution using gravimetric, open circuit potential and potentiostatic polarisation techniques. The percentage inhibition efficiency (g%) for each inhibitor increased with increasing concentration until the critical micelle concentration (cmc) was reached. The maximum inhibition efficiency approached 95.1% in the presence of 400 ppm of the inhibitor (IV). It was found that the adsorption of the surfactants on carbon steel followed the Langmuir adsorption isotherm. Potentiostatic polarisation data indicated that these surfactants act as mixed type inhibitors. The values of activation energy (E a *) of carbon steel dissolution in 1 M HCl were calculated in the absence and presence of 400 ppm of each inhibitor. Finally, scanning electron microscopy (SEM) was used to examine the surface morphology of polished carbon steel surfaces and those immersed in 1 M HCl in the absence and presence of 400 ppm of inhibitor (IV).

Electrochemical techniques and fractal theory were employed to study the corrosion behaviors and pits distribution characteristics on the corroded surfaces of 304 stainless steel exposed in FeCl 3 solution. Fractal features of pits distribution over the corroded surfaces were observed and described by the fractal dimension. A 5-8-2 back-propagation (BP) artificial neural network model for the diagnoses of the pitting corrosion rate and pits deepness of 304 stainless steel under various conditions was developed by considering the fractal dimension as a key parameter for describing the pitting corrosion characteristics. The predicted results are well in agreement with the experimental data of pitting corrosion rate and pit deepness. The max relative errors between their experimental and simulation data are 6.69% and 4.62%, respectively.
