Electrodeposited nickel matrix embedded with silicon carbide (SiC) and graphene oxide (GO) particles were prepared through pulsed electro-deposition. Taking advantages of the excellent tribomechanical properties of GO and SiC, excellent anti-wear and frictional properties are expected when SiC and GO particles were embedded in the Ni matrix. For this purpose, nano-SiC particles were first grafted within Ni matrix to engineer Ni-SiC coatings. Further GO particles were added to the Ni-SiC bath to prepare Ni-SiC-GO composite coating. The structure, composition, and morphology of the Ni-SiC and Ni-SiC-GO were characterized by Raman spectroscopy, XRD, AFM, FE-SEM, EDS and water contact angle measurements. The results revealed that SiC and GO particles were successfully incorporated in the Ni matrix. Addition of GO to the composite matrix reduced the water contact angle from 69.2°to 58.9°, thereby confirming hydrophilic nature of Ni-SiC-GO due to the presence of polar oxygen functionalities. The tribological tests of the coatings were studied under dry sliding condition using a linear reciprocating ball on plane sliding microtribometer with varying sliding speed and the wear mechanisms of these coatings were also investigated. The addition of SiC into the Ni matrix enhanced its wear resistance with a poor frictional behaviour. However, incorporation of GO into Ni-SiC-GO coatings reduced the coefficient of friction (COF) substantially with an adaptable anti-wear behaviour. Increase in sliding speed was found to have a detrimental effect in the wear and friction behaviour of the coatings. The superior tribological properties of the Ni-SiC-GO were attributed to the synergistic effects of SiC and GO. This work offers a unique methodology to design durable nanocomposite coatings for industrial tribological applications.

“…Several studies have demonstrated that electroplating by using pulse current technique results in the production of deposits with improved mechanical properties and with more uniformly distributed metal ions, in comparison with direct current technique [11][12][13][14]. Some important equations used in pulse electrodeposition are as follows [11]:…”

A copper-zinc bath containing EDTA was used for deposition of multi-functional copper-zinc coatings. Copper substrates were used for pulse electrodeposition of copper-zinc coating. Microhardness and wear resistance of copper-zinc coatings has been studied. The films were characterized by scanning electron microscopy and X-ray diffraction. EDS and EDS-dot mapping were also performed to analyse the amount and the distribution of Cu-Zn atoms.

“…Electroless plating is one of the most popular technology, which has been widely used as an effective way for surface-modification of CNTs because that it is much simpler, lower cost and without vacuum or high temperature. 1-6 The metallic ions change into metal and deposit on the substrate surface to form surface modified coating through the chemical reduction. 7-9 At present, most research activities have been focused on electroless Ni, Fe and alloy plating on CNTs, 10-14 and only limited research has been concerned with plating Co and Co–P alloy.…”

Continuous Co 2 P nanoparticles were deposited on the surfaces of carbon nanotubes (CNTs) with the thickness of 7-10 nm by electroless plating. Effects of pH, temperature and plating time on the coating were discussed and the optimised processing parameters were obtained. The morphologies and components of Co 2 P-CNTs nanocomposites were analysed by TEM and energy dispersive spectroscope. The results indicated that Co 2 P nanoparticles were deposited on multi-walled carbon nanotubes homogeneously at the temperature of 45°C, pH of 4.9 and plating time of 30 min. The saturation magnetisation of uniform Co 2 P-CNTs nanocomposites was 2.81 emu g -1 and the coercivity was as high as 1285.2 Oe. Compared to those of the bulk cobalt, the coercivity of Co 2 P-CNTs nanocomposites was enhanced while the saturation magnetisation decreased.
