Abstract

Cadmium sulfide nanoparticles (CdS) were effectively prepared using ultrasonication-assisted synthesis. The high hydrophobicity and excellent dispersibility of the synthesised CdS nanoparticles in ethanol could increase their anti-penetrant effect against corrosive media. We evaluated and examined the corrosion prevention properties of CdS nanoparticle coatings on MS steel using Tafel polarisation and electrochemical impedance spectroscopy in HCl, NaCl, and KOH. The experimental results demonstrated that CdS nanoparticle coatings had higher corrosion performance than uncoated MS plates. Besides, CdS nanoparticles may be adsorbed on steel to produce a hydrophobic anti-corrosion layer, enhancing corrosion resistance. The impedance of CdS coatings increased continuously during electrolyte immersion. The results show that CdS acted as a suitable inhibitor and this inhibition efficiency and the polarization curves indicated that CdS nanoparticles performed as mixed inhibitors. The inhibition effect on the surface of the MS plate using CdS nanoparticle coating was investigated with inhibitors confirmed by nanoindentation techniques. The revolutionary approach for creating hydrophobic CdS nanoparticles suggested in this exertion may stimulate the development of high-performance anticorrosion materials and their corrosive protection applications.

具有超疏水性和长期防腐性能的硫代镉离子研究

利用超声辅助合成法有效地制备了硫化镉纳米粒子（CdS）。合成的 CdS 纳米粒子在乙醇中具有很高的疏水性和良好的分散性，可以增强其对腐蚀性介质的抗渗透作用。我们利用塔菲尔极化和电化学阻抗谱在盐酸、氯化钠和氢氧化钾中评估和检验了 CdS 纳米粒子涂层在 MS 钢上的防腐蚀性能。实验结果表明，与未涂层的 MS 钢板相比，CdS 纳米粒子涂层具有更高的防腐蚀性能。此外，CdS 纳米粒子还可以吸附在钢材上产生疏水防腐层，增强耐腐蚀性能。在电解液浸泡过程中，CdS 涂层的阻抗持续增加。结果表明，CdS 是一种合适的抑制剂，这种抑制效率和极化曲线表明，CdS 纳米粒子具有混合抑制剂的作用。使用 CdS 纳米粒子涂层对 MS 板表面的抑制效果进行了研究，并通过纳米压痕技术对抑制剂进行了确认。本研究提出的创造疏水性 CdS 纳米粒子的革命性方法可促进高性能防腐材料的开发及其腐蚀防护应用。关键词：CdS 纳米粒子；低碳钢板涂层；防腐应用 Bull.Chem.Soc.2024, 38(5), 1493-1507.
