摘要
利用电沉积技术制备了以金属氧化物纳米颗粒增强的镍纳米复合镀层,从而提高了传统镍镀层的性能。通过改变二氧化硅纳米粒子的浓度,研究了外加电流密度的影响。利用 X 射线衍射仪和扫描电子显微镜分别对样品进行了相结构研究和形态学研究。利用维氏压痕法测定了纳米复合涂层的机械性能。电位极化技术用于评估纳米复合涂层的电化学行为。结果表明,在镍基体中引入 SiO 2 纳米粒子可以改善所制纳米复合涂层的机械性能和电化学性能。
Elektrokimyasal Olarak Çöktürülmüş Metal Oksit Takviyelendirilmiş Ni Nanokompozit Kaplamaların Korozyon Performansı
The properties of traditional nickel coatings were enhanced by preparing Ni nanocomposite coatings reinforced with metal oxide nanoparticles by using electrodeposition technique. The impact of applied current density was investigated by changing SiO2 nanoparticle concentration. Phase structure study and morphological investigation of the samples were performed by X-Ray Diffractometer and Scanning Electron Microscopy, respectively. Vickers indentation method was utilized to determine the mechanical properties of obtained nanocomposite coatings. Potentiodynamic polarization technique was performed to evaluate electrochemical behavior of nanocomposite coatings. As a result, introducing SiO 2 nanoparticles to Ni matrix improves both mechanical and electrochemical properties of produced nanocomposite coatings.
