“…M a n u s c r i p t stage is observed to replace an active stage that is characterized by a Tafel region, which is possibly related to the formation of a complete hydrophobic SAM on the steel surface [30]. It is interesting to note that the whole passive range is divided into two regions that are separated by a peak, which is a common observation.…”

“…The OCP decreased sharply from –0.018 V to –1.111 V with time at the first day. Such a reduction was caused by an accelerated anodic reaction rate, according to mixed potential theory [ 15 ]. Three days later, the OCP augment a little and then renewed to reduce.…”

With the continuous tightening marine diesel engines emission standards, removing sulfur oxides (SOX) by sodium hydroxide solution absorption is a highly efficiency and economic method, which has been a hot area of research. The ensuing desulfurization solution is a new corrosive system, the aim of this paper is to ascertain the corrosion feature of Q235B steel in desulfurization solution, which lays a theoretical foundation for industrialization. For this purpose, mass loss, electrochemical techniques and surface analyses were applied. The results of mass loss highlight a reduction in the corrosion rate with 35 days of immersion. Higher exposure time increased the compactness of the corrosion product layer and changed phase composition. These conclusions are supported by surface analyses, such as X-ray diffraction and scanning electron microscope. However, electrochemical results showed that the polarization resistance Rp was fluctuant. Both of Rp and charge transfer resistance Rt reach a maximum after immersing 21 days. In addition, although the sediments attached to the steel surface could inhibit corrosion, pitting corrosion aggravated by hydrolyzation of FeSO4 should be given more attention.

“…There is a shift in the cathodic region due to the adsorption factor of the inhibitor over the mild steel surface which is observed from the Ecorrvalues. 3 potentiodynamic polarization parameters are represented which shows variability on Tafel slopes and reveals that inhibitor at all concentrations at different temperatures shows the corrosion mechanism process at the cathode [33][34][35] . At three different temperatures in comparison, Icorr values decreased.…”

The aim of the present work was to study the corrosion inhibition of mild steel using organic inhibitors. The corrosion inhibition activity of a newly synthesized [4-(4-aminobenzoyl) piperazin-1-yl) (furan-2-yl) methanone (4-4-ABPFM) and [4-(4-aminophenyl) piperazin-1-yl) (furan-2-yl) methanone (4-4-APFM) was investigated on the corrosion of mild steel in 1N HCl at room temperature for two hours using different methods.Such as weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Organic Inhibitor (4-4-ABPFM) were prepared throughout condensation of hydrochloric acid and reduction reaction using the reagent SnCl2, compound (4-4-APFM) involved a two reaction sequence of nucleophilic aromatic substitution and nitro group reduction, characterized by Fourier transform infrared spectroscopy (FT-IR). Electrochemical polarization test was also conducted to confirm the effectiveness of inhibition. Morphology of sample surfaces was respectively examined by scanning electron microscope (SEM). The result shows that the inhibition efficiency increases significantly up to 80% [4-(4-aminobenzoyl) piperazin-1-yl) (furan-2-yl) methanone (4-4-ABPFM) and 73% [4-(4-aminophenyl) piperazin-1-yl) (furan-2-yl) methanone (4-4-APFM). The optimum efficiency is obtained at (4-4-ABPFM) concentration of 100 ppm for expositing time of 2 hours at room temperature. The polarization curve shows the inhibitor behaves as a mixed inhibitor with the dominant cathodic inhibition. The adsorption of optimum concentration of both the inhibitor on the surface of mild steel in 1N HCl solution follows Langmuir adsorption isotherm. The Surface condition is improved due to the adsorption and then formation of thin layer film protection in the surface of the mild steel. The synthesized compounds show an appreciable corrosion inhibition property for mild steel in 1N HCl medium at room temperature which varies in the order: (4-4-APFM) < (4-4-ABPFM) compound.
