Preparation and Characterization of Pulse Electrodeposited Ni/W-SiC Nanocomposite Coating on Mild Steel Substrate

In order to improve the performances of metal containers, furnace bodies and agricultural tools manufactured by mild steels, Ni/W-SiC nanocomposites are prefabricated on steel substrate pulse electrodeposition (PED) method. The morphology, texture, microstructure, microhardness, wear examined scanning electron microscopy (SEM), atomic force (AFM), X-ray diffraction (XRD), dispersive spectroscopy (EDX), hardness tester, friction testing. results indicate that SiC size in is ~32.4 nm when its concentration electrolytes 7 g/L. S1 S4 nanocomposites’ microstructures (the composite was at 4 g/L, deposited 13 g/L) reveal many large cauliflower-shaped grains. However, S2 nanocomposite obtained demonstrates homogeneous, finest smoothest surface morphology. angles 41.2°, 51.7°, 71.2° depicting sharpest peaks, corresponding (1 1 1), (2 0 0), 2 0) crystal planes Ni-W grains, respectively. Moreover, exhibits lowest depth width 34.2 μm 5.5 mm, Some shallow fine scratches as-described excellent tribological performance. a 86.3 11.9 mm.
