“…Further surface analysis by EDX spectra (Figure 10a, Figure 10b and Figure 10c) substantiate the significant increase in iron peak in inhibited specimen indicating retention of surface‐bound iron atoms in the presence of BMDP. The high carbon content on the inhibited surface (Table 9) signifies the adsorption of BDMP through carbon atoms, forming a protective layer [51] …”

“…The high carbon content on the inhibited surface (Table 9) signifies the adsorption of BDMP through carbon atoms, forming a protective layer. [51] The accurate roughness of the surface of the corroded surface was found using atomic force microscopy (IB342-Innova model AFM). The comparison of roughness values (Table 10) consisting of root mean square roughness (R q ), average roughness (R a ), maximum peak to valley height (R pÀ v ) and highresolution AFM images (Figure 11) reveal that the topography of inhibited specimen is smoother than the uninhibited surface.…”

A new pyrazoline derivative, 1-[5-(4-bromophenyl)-3-(6-methoxypyridine-3-yl)-4-5-dihydro-1H-pyrazol-1-yl]-ethane-1-one (BMDP) was synthesised using chalcone derivative. The FTIR, 1 HNMR, and mass spectral analysis were performed to validate the synthesised compound. The electrochemical impedance spectroscopy and potentiodynamic polarization techniques were performed to evaluate BMDP as a corrosion inhibitor for mild steel. The corrosion inhibition was observed to rise with an increase in BMDP concentration and decline with an increase in temperature. The maximum inhibition efficiency of 91.1 % was reported at 303 K in 40 ppm of BMDP concentration. Activation and adsorption parameters were found with statistical thermodynamic calculations. The surface investigation of the metal surface was performed by SEM, AFM and EDX techniques. UV-visible spectroscopy was used to realise the inhibitor-metal complex formation. The quantum chemical computations were performed by density functional theory using Gaussian 16 software, and the theoretical calculations confirm the outstanding anticorrosive property of BMDP at the diminutive level as analysed in electrochemical studies.

Corrosion is a destructive phenomenon which occurs spontaneously in the environment and leads to economic, environmental, and safety problems. The focus of recent studies in the field of corrosion is on replacing harmful inhibitors with biocompatible and cheap ones. In this research, the purpose is to synthesize a smart and self‐healing coating based on a poly dopamine biopolymer containing Bio‐MOF‐11@ nano‐curcumin as a green inhibitor. The characteristics and morphology of the synthesized materials and the effectiveness of these materials as corrosion‐protective coatings were investigated with various techniques including Fourier‐Transform infrared spectroscopy (FT‐IR), X‐Ray diffraction (XRD), ultraviolet–visible spectroscopy (UV–vis), scanning electron microscopy (SEM), and energy dispersive X‐Ray analysis (EDS). The UV–vis technique was also used to evaluate the effect of the inhibitor release at pH 4 and 7. The maximum amount of the inhibitor release after 72 hours was 86.61 ppm at pH 4.0. The corresponding electrochemical studies were conducted through electrochemical impedance spectroscopy (EIS) and Tafel plot. Finally, the inhibition rate of the coating was found to be 95.08%, which indicates the good performance of the PDA@Bio‐MOF‐11@Cur NPs coating for corrosion protection of MS in 3.5% NaCl.
