عنوان انگلیسی Development of a Robust Self-Healing Anticorrosion Coating via One-Pot Electrochemically Deposited SiO2/Linseed on Carbon Steel Electrode
چکیده انگلیسی مقاله This work presents a novel self-healing/anti-corrosion coating based on epoxy resin decorated with electrochemically deposited silicon dioxide (SiO2)/linseed oil (LO). For this purpose, the SiO2/LO composite was prepared via a one-pot electrochemical deposition method, which was then utilized as a precursor for epoxy coating preparation. Various techniques, including Fourier Transform InfraRed (FT-IR) spectroscopy, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray spectroscopy (EDS), ThermoGravimetric Analysis (TGA), and X-Ray Diffraction (XRD) analysis were used to characterize the coated steel samples. Corrosion current and corrosion potential were decreased following the addition of SiO2 and LO to the steel surface. The mechanism of improved anticorrosion performance of the composite coating can be attributed to the synergistic effect of the components within the composite film. The effect of various coatings on the anticorrosive characteristics of the self-healing coatings has been investigated by electrochemical impedance spectroscopy (EIS), Tafel plots, salt spray, and optical images. The defected self-healing coating consisting of epoxy/SiO2/LO exhibited exceptional healing ability and corrosion inhibition performance toward steel metal as evidenced by EIS and optical images. The SiO2/LO coating layer shows the lowest corrosion current of 0.091 µA/cm2 compared to SiO2 with 0.822 µA/cm2 in corrosive saline media. Furthermore, epoxy-coated SiO2/linseed oil and epoxy-coated SiO2 films on steel supports exhibit corrosion resistances of 1.95×108 and 7.20×107 Ω/cm2 demonstrating better performance of silica-containing linseed oil. It seems that the addition of a hydrophobic linseed oil component can successfully delay the diffusion of water molecules or electrolyte ions, resulting
in the improvement of anticorrosion characteristics of the coating layer.
