The present work describes green-mediated copper oxide nanoparticles as a potential corrosion inhibitor for the dental alloy Ti-6Al-4V. The salt of copper was reduced to metal nanoparticles using Murraya koenigii leaves, which helps with the agglomeration and nanocluster formation through a reduction mechanism. The current synthesis is a single-step process and is cost-effective. The synthesized nanoparticle was characterized using UV, FTIR, XRD, Zeta potential and Particle size analyzer, SEM, and EDX. The particles were then electrodeposited on Ti-6Al-4V alloy, and the corrosion resistivity in the dental medium was analyzed using Electrochemical parameters such as Corrosion current, Corrosion potential, and anodic and cathodic intercepts through the Tafel and Nyquist plots. The synthesized nanoparticles showed characteristic absorbance at 359 nm. FTIR peaks confirm the phytochemical constituents present in the Murraya koenigii that accounts for the formation of nanoparticles. The XRD predicts the crystalline nature, which is further studied using SEM and EDX. The Zeta potential and Particle size analyzer confirms the negative-negative interactive nature of the synthesized CuO NPs. The NPs showed explicit corrosion inhibition properties with an overall inhibition efficiency of 58.15% and 25.6%, respectively. The study confirms the advantage of using Copper Oxide nanoparticles as a potential coating agent in dental implant alloys in increasing its corrosion efficiency.
本工作描述了氧化铜纳米粒子作为牙科合金 Ti-6Al-4V 的潜在腐蚀抑制剂。铜盐通过 Murraya koenigii 叶片还原为金属纳米粒子，通过还原机制有助于团聚和纳米簇形成。目前的合成是一个单步过程，具有成本效益。使用 UV、FTIR、XRD、Zeta 电位和粒径分析仪、SEM 和 EDX 对合成的纳米粒子进行了表征。然后将纳米粒子电沉积在 Ti-6Al-4V 合金上，并通过 Tafel 和 Nyquist 图中的腐蚀电流、腐蚀电位和阳极和阴极截距等电化学参数分析牙科介质中的耐腐蚀性。合成的纳米粒子在 359nm 处显示出特征吸收。FTIR 峰证实了 Murraya koenigii 中存在的植物化学成分，这是纳米粒子形成的原因。XRD 预测了晶体性质，进一步使用 SEM 和 EDX 进行了研究。Zeta 电位和粒径分析仪证实了合成的 CuO NPs 的负负相互作用性质。纳米粒子表现出明显的腐蚀抑制性能，总抑制效率分别为 58.15%和 25.6%。该研究证实了在牙科植入合金中使用氧化铜纳米粒子作为潜在涂层剂来提高其腐蚀效率的优势。
