“… 49 Generally, physisorption (electrostatic interaction) of an inhibitor on a metal surface is identified when Δ G ads is over −20 kJ mol −1 , while it can be considered as chemisorption (involving charge transfer) when Δ G ads is more negative than −40 kJ mol −1 . 50 Particularly, the obtained Δ G ads values are in the range of −20 and −40 kJ mol −1 , revealing that the adsorption of SPRE on the C-steel surface involves both physisorption and chemisorption. 3 Further inspection of Δ G ads indicates that the absolute value increases with an increase in temperature.…”

“…As is known, DS ads can be roughly deemed as the algebraic sum of the contributions from inhibitor adsorption and desorption of water molecules. 50 Therefore, the positive DS ads reveals that the regularity of the assembled SPRE constituents is inferior to the irregularity caused by the desorption water molecules. Furthermore, the negative DH ads and positive DS ads are typical characteristics for a spontaneous reaction, 29 which are consistent with the analysis of DG ads .…”

“…[N.B. : On the basis of previous work (e.g., ref 27), we expect such a sample to be terminated by a several nanometer thick layer of oxidic iron, along with a topmost film of adventitious carbon.] Diffraction measurements from these samples were performed by employing synchrotron radiation (SR) from beam line BM28 (XMaS) at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France.…”

Controlling corrosion with naturally occurring corrosion scales is potentially a more environmentally sustainable alternative to current approaches, including dosing of organic corrosion inhibitors. We report operando grazing incidence X-ray diffractograms correlated with electrochemical measurements to elucidate the growth and corrosion protection properties of a corrosion scale composed of FeCO 3 crystallites, which is encountered in various key energy industry applications. Data, acquired as a function of time from high-purity iron immersed in CO 2 -saturated deionized H 2 O at pH 6.8 and T = 80 °C, show that the FeCO 3 scale not only prevents corrosion of the covered substrate but also acts as a significant interfacial diffusion barrier for corrosion reagents and/or products once sufficient coverage is achieved. Most notably, from a corrosion engineering perspective, however, it is determined that corrosion occurring in gaps between scale crystallites remains appreciable; this important insight is gained through the analysis of electrochemical impedance spectra to estimate the variation in electrochemically active surface area as scale coverage increases. These results indicate that naturally occurring FeCO 3 scales are not a tenable solution for corrosion protection, as even in their intact state they are highly likely to be, at best, semiprotective.

“…Especially, they are usually used in acidic media (Tang et al, 2011). Kousar et al (2021) reported that an imidazoline-based surfactant with alkyl chain of 17 C achieved excellent performance in 1 M HCl. On account of the steric effect of the alkyl chain, both water molecules and the corrosive particles can be hindered.…”

Purpose This paper aims to discover a highly efficient corrosion inhibitor for 45# steel in hydrochloric acid solution and reveal the mechanism of inhibitors. Design/methodology/approach In this paper, electrochemical measurements, weight loss measurements, surface characterization and theoretical calculation are used to evaluate the inhibition performance and reveal the mechanism of inhibitors. Findings Results show that didecyl dimethyl ammonium chloride (DDAC), especially in combination with dodecane phenol plyoxyethylene, could provide a good protection performance for the carbon steel in hydrochloric acid. The N atoms and long alkyl chains in DDAC molecular structure play the vital role. Originality/value Usually, DDAC is used as the compound chemical disinfectant in oilfield sterilization, medicine and health. However, to the best of the authors’ knowledge, no study has shown that it can mitigate the corrosion of carbon steels in HCl solution.
