Innovative Modifications to Commercial Paints for Superior Corrosion Protection of Carbon Steel
摘要
This study investigates the anticorrosion performance of commercial paint enhanced with nano-oxide particles and two-dimensional (2D) materials, applied to carbon steel immersed in a sodium chloride (NaCl) solution. Various electrochemical techniques, including open circuit potential (OCP) measurements, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization (PDP), were employed to evaluate the protective efficiency of the modified coatings. The findings indicate that the incorporation of TiO2 nanoparticles enhances the corrosion resistance of carbon steel, as evidenced by the promotion of stable passive layer formation, thereby reducing metal dissolution. Furthermore, profilometry analysis demonstrates that nano-oxide-modified coatings exhibit superior scratch resistance compared to 2D materials, contributing to their enhanced durability. The findings were further validated through accelerated salt spray testing, which demonstrated the prolonged corrosion resistance of samples coated with ZnO–SrCrO4 formulations. These results underscore the potential of nanomaterial-enhanced coatings to improve the longevity and corrosion resistance of carbon steel in harsh environments, making them promising candidates for industrial applications.
