Composite coatings based on nickel have recently become popular in the automotive and aerospace industries owing to their corrosion-resistant qualities. However, as many cases have shown, this coating is ineffective in chloride-containing environments. As remediation, a graphene oxide/conducting polymer (Polypyrrole) composite with nickel has been proposed as an effective corrosion protective layer for bare mild steel. Furthermore, electrodeposition is one of the popular methods for coating metals with anti-corrosion coatings. A simple, costeffective, and environmentally friendly electrodeposition process has been employed for the deposition of graphene oxide/polypyrrole composite with nickel (Ni-GO-PPy) on mild steel. XRD, EDAX, FE-SEM, and FT-ATR were used to analyze this coating extensively. A coated mild steel sample was evaluated in a 3.5% NaCl solution utilizing the Potentiodynamic polarization ,electrochemical impedance spectroscopy and weight loss immersion test to determine the coatings' anti-corrosion characteristics. In all of the experiments, the Ni-GO-PPy coating outperformed bare nickel and Ni-GO coatings in terms of anti-corrosion capabilities. As a result of this research, a practical and scalable technique for using Ni-GO-PPy composite coating to protect mild steel surfaces against corrosion has been demonstrated.
