Characterization of Ni-Fe/Si{sub 3}N{sub 4} Nanocomposite Coatings Deposited by Electroplating
- Center for Nanotechnology, Precision and Advanced Materials, University of Malaya, 50603 Kuala Lumpur (Malaysia)
Ni-Fe/Si{sub 3}N{sub 4} nanocomposite coatings with various amount of Si{sub 3}N{sub 4} were prepared by electrodeposition technique. The effect of Si{sub 3}N{sub 4} nanoparticulates in the Ni-Fe nanocomposite coatings was investigated in relation to the ratio of Si{sub 3}N{sub 4} 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 Si{sub 3}N{sub 4} to Na-saccharine was around 8.3. The crystallite size of the Ni-Fe nanocomposite coating decreased when the ratio of Si{sub 3}N{sub 4} 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 Si{sub 3}N{sub 4} and this contributed in increasing the microhardness of coating.
