“…5). This phenomenon indicates that propolis molecules form a barrier on the steel surface and thus protect it from corrosion [29]. The deviation of the maximum of Nyquist curve from the ideal semicircle could be due to the imperfection of the electrode surface or inhibitor adsorption [30,31].…”

This paper studies the corrosion inhibition of X52 5L carbon steel in 0.51 mol dm-3 sodium chloride solution in the presence of propolis extract. The inhibition efficiency of propolis extract in a chloride solution was tested by its adding to the working solution and by making a solid propolis coating on the electrode surface. The possibility of corrosion inhibition in the presence of propolis in flow conditions as well as at different temperatures was investigated by electrochemical methods: potentiodynamic polarization method and electrochemical impedance spectroscopy. It was shown that propolis extract acts as a corrosion inhibitor of anodic type whose efficiency increases with increasing of temperature and with stirring of solution. The best protection is achieved by applying propolis coating in flow systems. The EIS method confirmed formation of a protective layer by adsorption of propolis extract on the electrode surface. The results of the FTIR, SEM and EDX surface tests are consistent with the results of electrochemical testing and suggest that propolis extract acts as a corrosion inhibitor of steel by forming a protective film on the electrode surface.

“…b. Surfactant aggregation study: The ability of effective corrosion inhibition by a surfactant compound has been reported to depend strongly on aggregation [42], which is related to properties of the studied system, such as pH and tem perature. There are various corrosion inhibitor molecules that have been studied, for example using electrochemical impedance spectroscopy, but no studies applied both the SAXS and SANS techniques, leaving a gap in understanding of their in hibition mechanisms.…”

This chapter presents advances in the characterization of surfactants and detergents using small angle X-ray scattering (SAXS) and small angle neutron scattering (SANS) techniques. Surfactant molecules have been extensively used for corrosion prevention as part of commercial corrosion-inhibitor formulations. It is generally established that the interactions between surfactant molecule and metallic substrate play a key role in the formation of a corrosion-protective film. It is therefore essential to develop understanding about the nature of surfactant and detergent molecules in bulk solutions prior to formation of a surface film, as well as the mechanisms of their interactions with metallic substrates. These properties and interactions determine the properties of the surface film, including its persistency, and in turn define its protectiveness against corrosion. X-ray and neutron reflectivity methods are important investigating tools that could be used to characterize surfactant interactions with metallic substrates. These techniques have recently been utilized to investigate adsorption energies and contact angles between molecules or particles and variable substrates. This chapter addresses basic principles of these techniques and discusses their application for surfactant and detergent studies in corrosion science. Several case studies are presented and provide outlook for future prospects in this field of science.

“…In recent years, the study of corrosion inhibition performance using Gemini surfactants is more prevalent (Al‐Amiery et al, ; Asefi and Mahmoodi, ; Cao and Hou, ; Du et al, ; Hegazy and Abdallah, ; Qiu et al, ; Qiu and Lv, ; Song et al, ; Wang et al, ; Xia et al, , ; Zhang et al, , ). Most studies have focused on the corrosion inhibition performance of steel.…”

A new corrosion inhibitor was synthesized from chloroacetyl chloride, 1,3‐propanediamine, and dodecyldimethyl tertiary amine. The structure of the synthesized product was characterized using Fourier transform infrared(FTIR). The critical micelle concentration (CMC) was determined from surface tension measurements. The inhibition behavior of the corrosion inhibitor for 2024 Al‐Cu‐Mg alloy was studied using the weight‐loss method and electrochemical measurements in hydrochloric acid solution. Experimental results show: The CMC is 7.767 × 10−4 mol L−1 and IE (C pro = 1 × 10−3 mol L−1) ≈ 87.9%. The adsorption free energy is calculated to be −33.12 kJ mol−1. Therefore, the adsorption mode is more inclined to physical adsorption. When the concentration of the synthesized product is lower than the CMC, it satisfies the Langmuir adsorption model; when the concentration is higher than the CMC, it no longer follows the Langmuir adsorption model.
