Fabrication kinetics and properties of Ni-based nano-arrays embedded in anodic Al2O3 film

By direct current electrodeposition technique combined with the anodic aluminum oxide films, Ni-based nano-arrays were successfully performed. The structure was studied by X-ray diffraction and high-resolution transmission electron microscopy with selected-area electron diffraction. Energy dispersive spectroscopy was used to prove the composition of the prepared nanowires. The magnetic property curves of Ni-based nano-arrays were measured by a physical property measurement system. According to electrochemical analysis, the growth kinetics of the nanowires was studied by determining the relationship between the current and time under different parameters, such as electrolyte temperature and electrodeposition voltage.
