“…The R ct values increase when the CPYA concentration increases, leading to a greater number of organic molecules adsorbed on the MS surface, resulting in an efficient metal surface protection. The maximum anticorrosive efficiency of 95.3% was obtained by CPYA at 4.59 mmol/L, corroborating the results from the weight loss method . All data are shown in Table .…”

“…Density functional theory (DFT) is a theoretical method extensively used in analyzing the inhibitor/surface interaction. These characteristics can be used to explain the structural properties present on an inhibitor with the corrosion process . Some quantum chemical parameters ( E LUMO , E HOMO , energy gap, and dipole moment) have been used frequently to evaluate the relationship between organic molecules and the steel surface.…”

4‐Chloro‐N‐(pyridin‐2‐ylmethyl)aniline (CPYA) was synthesized by a simple and inexpensive method and tested as a corrosion inhibitor in acid medium for mild steel by using gravimetric studies and electrochemical measurements. An average maximum efficiency of 96.0% was achieved at 4.59 mmol/L. Corrosion kinetic and thermodynamic parameters were also analyzed. Surface analyses (atomic force microscopy and scanning electron microscopy) show that protection is enabled by adsorption on the metal, forming a film. Quantum chemical calculations were performed to access information regarding the molecular structure in the corrosive medium and to support interpretation of the results obtained by experimental methods.

“…A broad range of applications of Schiff bases and their metal complexes have been reported by several studies, which including catalytic properties, bioactivity and corrosion inhibiting ability [12], [15], and [18]. Schiff bases possess as an effective anti-corrosion agents for protection of metals like mild steel, aluminium and copper surface [11], [19], [21]. The existence of electrodeposited layer of inert organic layer such as Schiff bases on mild steel surface can protect it from corrosive medium environment [13].…”

Two Schiff bases namely (E)-2-((phenylimino)methyl) phenol (SA1) and (E)-2-methoxy-6-((phenylimino)methyl) phenol (SA2) were produced via reaction of phenylamine with 2-hydroxybenzaldehyde and 2-hydroxy-3-methoxybenzaldenyde, respectively. The structures were elucidated through spectral and physicochemical techniques of melting point, elemental analysis (C, H and N), 1H Nuclear Magnetic Resonance (NMR) and Infrared (IR) spectroscopy. The distinctive n(C=N) and d(OH) peaks for SA1 and SA2 appeared at 1615 and 1613 cm-1 and at 13.27 and 13.37 ppm, respectively. Electrodeposit both compounds on mild steel at 0.05 M concentration in 0.3 M NaOH was established through cyclic voltammetry (CV) and chronoamperometry (CA) methods. Yellow and brownish Schiff base layers were observed to be formed on the mild steel specimens. The coated and uncoated mild steel specimens were tested for their corrosion behavior using the Tafel Extrapolation Method (TEM) in 0.5 M NaCl. Results demonstrated that mild steel coated with SA2 through CA technique at potential +0.90 V showed the highest inhibition efficiency, hence indicating a superior surface coverage, with 97.20 % inhibition efficiency; while SA1 recorded the highest inhibition efficiency of 93.83 % at coating potential of +1.35 V.

A novel and simple method to improve the corrosion resistance of copper by constructing a 3D 1-dodecanethiol self-assembled monolayers (SAMs) in 3.5% NaCl solution is reported in this study. Several drops of 1% H3PO4 solution are thinly and uniformly distributed on copper surface to form a 3D nanostructure constituted by Cu3(PO4)2 nanoflowers. The anticorrosion properties of 1-dodecanethiol SAMs on copper surface and on copper surface treated with H3PO4 solution were evaluated. Results demonstrated that 1-dodecanethiol SAMs on bare copper surface exhibit good protection capacity, whereas a copper surface pretreated with H3PO4 solution can substantially enhance the corrosion resistance of 1-dodecanethiol SAMs.
