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, cost-effective, 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.

基于镍的复合涂层最近因其耐腐蚀特性而在汽车和航空航天工业中流行起来。然而，正如许多案例所表明的那样，这种涂层在含氯环境中是无效的。作为补救措施，已提出一种含镍的氧化石墨烯/导电聚合物（聚吡咯）复合材料作为裸露低碳钢的有效腐蚀保护层。此外，电沉积是用防腐涂层涂覆金属的流行方法之一。一种简单、经济且环保的电沉积工艺已被用于在低碳钢上沉积氧化石墨烯/聚吡咯与镍 (Ni-GO-PPy) 复合材料。XRD、EDAX、FE-SEM 和 FT-ATR 被广泛用于分析该涂层。涂层低碳钢样品在 3 中进行了评估。5% NaCl 溶液利用动电位极化、电化学阻抗谱和失重浸泡试验来确定涂层的防腐特性。在所有实验中，Ni-GO-PPy 涂层在防腐能力方面优于裸镍和 Ni-GO 涂层。作为这项研究的结果，已经证明了一种使用 Ni-GO-PPy 复合涂层保护低碳钢表面免受腐蚀的实用且可扩展的技术。
