This research work describes the effect of dispersed titanium carbide (TiC) nanoparticles into nickel plating bath on Ni/TiC nanostructured composite layers obtained by electro-codeposition. The surface morphology of Ni/TiC nanostructured composite layers was characterized by scanning electron microscopy (SEM). The composition of coatings and the incorporation percentage of TiC nanoparticles into Ni matrix were studied and estimated by using energy dispersive X-ray analysis (EDX). X-ray diffractometer (XRD) has been applied in order to investigate the phase structure as well as the corresponding relative texture coefficients of the composite layers. The results show that the concentration of nano-TiC particles added in the nickel electrolyte affects the inclusion percentage of TiC into Ni/TiC nano strucured layers, as well as the corresponding morphology, relative texture coefficients and thickness indicating an increasing tendency with the increasing concentration of nano-TiC concentration. By increasing the amount of TiC nanoparticles in the electrolyte, their incorporation into nickel matrix also increases. The hybrid Ni/nano-TiC composite layers obtained revealed a higher roughness and higher hardness; therefore, these layers are promising superhydrophobic surfaces for special application and could be more resistant to wear than the pure Ni layers.
本研究工作描述了将分散的碳化钛（TiC）纳米颗粒加入到镀镍液中对通过电共沉积获得的Ni/TiC纳米结构复合层的影响。通过扫描电子显微镜（SEM）对Ni/TiC纳米结构复合层的表面形貌进行了表征。利用能量色散X射线分析（EDX）研究并估算了涂层的成分以及TiC纳米颗粒在Ni基体中的掺入百分比。应用X射线衍射仪（XRD）来研究复合层的相结构以及相应的相对织构系数。结果表明，添加到镍电解液中的纳米TiC颗粒浓度会影响TiC在Ni/TiC纳米结构层中的掺入百分比，以及相应的形貌、相对织构系数和厚度，且随着纳米TiC浓度的增加呈现出上升趋势。通过增加电解液中TiC纳米颗粒的量，它们在镍基体中的掺入量也会增加。所获得的Ni/纳米TiC混合复合层显示出更高的粗糙度和硬度；因此，这些层有望成为用于特殊应用的超疏水表面，并且可能比纯Ni层更耐磨。
