“…Organic substances known as Schiff bases have numerous uses in biology and materials research [25,26]. Schiff-based cationic surfactants can adsorb onto metal surfaces by charge-transfer complex bonds between the polar groups of Schiff base and metal surfaces [27,28]. Cationic surfactants bearing Schiff base moiety proved high efficiency in an acidic solution, where a nitrogen atom is accomplished to form coordinate covalent bonds with the steel interface by its unshared, lone pairs of electrons, whereas the π-bond interacts physically, increasing their adsorption attraction to the metal interface.…”

Novel imine-tethering cationic surfactants, namely (E)-3-((2-chlorobenzylidene)amino)-N-(2-(decyloxy)-2-oxoethyl)-N,N-dimethylpropan-1-aminium chloride (ICS-10) and (E)-3-((2-chlorobenzylidene)amino)-N,N-dimethyl-N-(2-oxo-2-(tetradecyloxy)ethyl)propan-1-aminium chloride (ICS-14), were synthesized, and the chemical structures were elucidated by various spectroscopic approaches. The surface properties of the target-prepared imine-tethering cationic surfactants were investigated. The effects of both synthesized imine surfactants on carbon steel corrosion in a 1.0 M HCl solution were investigated by weight loss (WL), potentiodynamic polarization (PDP), and scanning electron microscopy (SEM) methods. The outcomes show that the inhibition effectiveness rises with raising the concentration and diminishes with raising the temperature. The inhibition efficiency of 91.53 and 94.58 % were attained in the presence of the optimum concentration of 0.5 mM of ICS-10 and ICS-14, respectively. The activation energy (Ea) and heat of adsorption (Qads) were calculated and explained. Additionally, the synthesized compounds were investigated using density functional theory (DFT). Monte Carlo (MC) simulation was utilized to understand the mechanism of adsorption of inhibitors on the Fe (110) surface.

“…As one factor of surface integrity, the surface roughness greatly affects surface corrosion. Based on the results of electrochemical polarization tests, Prakash et al associated surface roughness with surface strain, and emphasized the increase of surface activity as enlarging surface roughness, which signified corrosion more easily occurs. Moreover, the corrosion resistance of AlSi10Mg alloy in 3.5% sodium chloride solution was improved when surface was polished to be smoother .…”

Al–Li alloy 2A97 is one promising alloy that could be widely used in the aerospace field to achieve weight lighting. Due to the addition of lithium element, its anticorrosion attracts widespread interest. In this study, the milled surfaces and ground‐polished surfaces of alloy 2A97 are characterized and compared from three aspects of surface integrity, namely surface roughness, residual stresses, and work‐hardening. After potentiodynamic polarization measurements that were conducted on the machined samples with different surfaces in 3.5 wt% sodium chloride solution, the corrosion parameters regarding corrosion thermodynamics and kinetics are analyzed. Experimental results reveal that the surface micro‐hardness of the milled surfaces is greater than that of the ground‐polished surfaces because of the plastic deformation induced by milling process. Work‐hardening is beneficial while increasing surface roughness is detrimental to anticorrosion of alloy 2A97, and the effect of surface residual stresses is insignificant. Moreover, the corrosion parameters and surface corrosion morphology indicate that the corrosion resistance of Al–Li alloy 2A97 underwent milling process is superior than that obtained by grinding and subsequently polishing, which could further promote the application of mechanical milling Al–Li alloy process in aerospace industry.
