The present work aims to study the influence of direct current and pulse current techniques as well as embedded SiC nanoparticles on the mechanical properties of the electrodeposited Ni-W coating.The electrodeposited coatings were studied for morphological,microstructural,mechanical,and scratch resistance properties using the surface roughness tester,scanning electron microscopy,energy-dispersive X-ray spectroscopy,X-ray diffraction,Vickers microhardness,and scratch tester.Application of pulse current exhibited relatively homogeneous and smooth surface of the coatings.A remarkable increment of microhardness was observed in both Ni-W and Ni-W-SiC coatings prepared under pulse current as compared to the direct current technique.Similarly,the scratch test revealed a considerable improvement in the scratch resistance behavior of the Ni-W alloy and the composite coatings from the pulsed current condition.Hence,the application of pulse current not only improved the surface-and microstructure-related properties but also enhanced the Vickers microhardness and scratch resistance properties of the coatings.In addition,the reduction in micro-cracks revealed the improvement in scratch resistance properties of the coatings due to the incorporated SiC nanoparticles into the Ni-W alloy matrix.
