“…Ultrasound is often applied to prepare a stable suspension of ceramic particles in the electrolyte solution prior to the composite plating, whereas the use of US treatment during electrolysis is not common. However, some reports indicate a beneficial effect of US-assisted electrodeposition of composites compared to the conventional silent procedure [34][35][36]. The propagation of US waves in the plating bath generates high pressure, causing stress that promotes the separation of individual nanoparticles from agglomerates [36].…”

“…Electrodeposited Ni-based composites coatings [1] have received a wide attention from the research community in recent years due to the enhanced tribological performance that such coatings may exhibit in terms of coefficient of friction (CoF) and wear resistance [2][3][4][5][6]. Nevertheless, most of the studies available in the literature deal with the performance of Ni-based composite coatings with hard particles, whereas the incorporation of inherently soft and lubricant particles such as hBN or WS 2 into electrodeposited Ni-based coatings has been studied to a much lesser extent [7,8], despite of the enhancement of both CoF and wear resistance that could be expected when lubricant particles [9] are incorporated into Ni coatings.…”

Abstract:The present study is focused on the evaluation of the tribological performance of novel Ni/hBN and Ni/WS 2 composite coatings electrodeposited from an additive-free Watts bath with the assistance of ultrasound. Lubricated and non-lubricated scratch tests were performed on both novel composite coatings and on standard Ni deposits used as a benchmark coating to have an initial idea of the effect of the presence of particles within the Ni matrix. Under lubricated conditions, the performance of the Ni/hBN composite coating was very similar to the benchmark Ni coating, whereas the Ni/WS 2 behaved quite differently, as the latter did not only show a lower coefficient of friction, but also prevented the occurrence of stick-slip motion that was clearly observed in the other coatings. Under non-lubricated conditions, whereas the tribological performance of the Ni/hBN composite coating was again very similar to that of the benchmark Ni coating, the Ni/WS 2 composite coatings again showed a remarkable enhancement, as the incorporation of the WS 2 particles into the Ni coating not only resulted in a lower coefficient of friction, but also in the prevention of coating failure.

“…A large number of ceramics particles incorporated with nickel matrix have also been reported in literatures (Shi et al, 2005, Gyawali et al, 2010, Garcia-Lecina et al, 2012. Besides this, SiC particles have also been extensively studied due to the cost effectiveness and wider applications (Shi et al, 2005, Gyawali et al, 2010, Garcia-Lecina et al, 2012. Nickel sulfamate is a commonly used electrolyte during the electroplating of nickel due to its high deposition rate and superior throwing power.…”

Nickel-Silicon Carbide (Ni-SiC) composite coating has been prepared by two electrode electrochemical codeposition technique in nickel sulfamate bath. The Cetyltrimethylammonium bromide (CTAB) was added in bath as cationic surfactant whereas saccharine as a grain modifier. The effect of current density during deposition was systematically studied and optimized to get homogeneous surface texture with utmost microhardness and deprived coefficient of friction. The result revealed that 60 mA/cm 2 current density was found to be the optimum current density which showed the highest microhardness of 590 ± 10 Hv and lowest coefficient of friction with regular surface morphology.
