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.

“…The results indicated that the incorporation of Si 3 N 4 particles enables an increase in the thermal stability of coatings and reduces its electrical resistivity compared to the bulk nickel. Gyawali et al [22] confirmed that the scratch resistance of the deposited Ni-W coating were greatly improved through incorporating Si 3 N 4 . While synthesis of various Ni-based composite coatings co-deposited with Si 3 N 4 nanoparticles using electrodeposition method have been widely reported [16][17][18][19][20][21][22], no systematic investigation is about the effect of plating conditions (duty cycle, frequency, current pattern and presence of Si 3 N 4 nanoparticles) on the development of microstructure and mechanical properties of the Ni-W-Si 3 N 4 coatings.…”

“…He et al [22] produced Ni-W-MWCNT coatings by pulse electrodeposition and reported that the corrosion resistance was improved after incorporation of MWCNT. Gyawali et al reported [23] that Ni-W-Si 3 N 4 coatings produced by electrodeposition and optimum content of the particles in the matrix results in coating with better hardness and elastic modulus. Li et al [24] reported Ni-W/SiC coatings produced by pulse electrodeposition and found that the concentration of ceramic particles in the electrolyte significantly affects the wear performance.…”

Nickel-Tungsten-Titanium carbide (Ni-W-TiC) coatings were produced by pulse electrodeposition from a Ni-W electrolyte containing TiC particles. The effects of TiC concentration in the electrolyte on the morphology, crystallite size, microstrain, mechanical, tribology and electrochemical properties of TiC reinforced Ni-W co-depositions were investigated. The highest hardness of 8.3 GPa and modulus of elasticity of 207 GPa were observed in the case of the coating produced at 15 g/L TiC concentration in the electrolyte. The increase in the H/E and H 3 / E 2 ratios led to displaying excellent wear resistance of the Ni-W-TiC co-depositions besides high resistance to plastic deformation. A direct correlation was observed between nanoindentation and wear resistance results of reinforced TiC co-depositions. It has also been shown by electrochemical impedance spectroscopy and potentiodynamic polarization analysis that TiC particles can improve the electrochemical properties of the co-depositions because of their barrier effect.
