Description
Ni-Fe/Si3N4 nanocomposite coatings with various amount of Si3N4 were prepared by electrodeposition technique. The effect of Si3N4 nanoparticulates in the Ni-Fe nanocomposite coatings was investigated in relation to the ratio of Si3N4 to Na-saccharine in the plating bath. X-ray diffraction analysis showed that the Ni-Fe nanocomposite coating has face-centered cubic structure (FCC). However, a mixture of body-centered cubic (BCC) and face-centered cubic (FCC) phases was observed when the ratio of Si3N4 to Na-saccharine was around 8.3. The crystallite size of the Ni-Fe nanocomposite coating decreased when the ratio of Si3N4 to Na-saccharine was increased. From the results of the elemental mapping procedure, it was found that inclusions of silicon were uniformly distributed in Ni-Fe composite coating, indicating good dispersion of Si3N4 and this contributed in increasing the microhardness of coating.
