In the present study, a nanocrystalline Ni-Fe matrix with reinforced TiO2 nanoparticles as a functional nanocomposite material was fabricated by pulsed current electroforming in UV-LIGA (lithography, electroplating, and molding). The influences of TiO2 nanoparticles on the Ni-Fe nanocomposite deposition were also investigated using scanning electron microscopy, transmission electron microscopy, and in vitro cytotoxicity assay. It was found that the Ni-Fe nanocomposite with 5 wt.% TiO2 nanoparticles showed a smooth surface and better dispersion property. When the Ni-Fe nanocomposite is combined with 20 wt.% TiO2, it resulted in congeries of TiO2 nanoparticles. In addition, TiO2 nanoparticles possessed better dispersion properties as performed in pulse current electrodeposition. The microstructure of the electrodeposited Ni-Fe-TiO2 nanocomposite was a FeNi3 phase containing anatase nano-TiO2. Moreover, the electrodeposited Ni-Fe-5 wt.% TiO2 nanocomposite exhibited a smooth surface and structural integrity. Cytotoxicity assay results also proved that the Ni-Fe nanocomposite with different concentrations of TiO2 nanoparticles had good biocompatibility. Therefore, the optimization of pulse current electroforming parameters was successfully applied to fabricate the Ni-Fe-TiO2 nanocomposite, and thus could be used as an endodontic file material for dental applications.
