“…The wear loss of the Ni-TiO2 nano-coating was smaller than the Ni-coated samples due to the present second phase reinforcement layer, which often served as a stable lubricant among contact surfaces [10]. Wang et al reported an improvement in TiO2 content from Ni-0 g/L TiO2 to Ni-10 g/L TiO2 nano composite coating reduced friction coefficient and weight loss following an improvement in TiO2 concentration which increased the wear rate by an increase in TiO2 lead porous structure decreased wear resistance [11].…”

The Ni-TiO2 nano-coatings were prepared on the AISI 1022 carbon steel (CS) surface using the pulse electrodeposition method. The surface structure of CS was considerably reformed owing to the titanium particles presence. The electroplating is widely used as a protection of the material surface to expand the life of vehicle components. The parameters of pulse frequency (PF - Hz), current density (CD - A/cm2) and duty cycle (DC - %) are combined into the RSM three factors and three level arrays to find the effect of the wear rate coating parameters. The Ni-TiO2 nano-particles deposited surface structure and wear of the surface were examined by field emission scanning electron microscopy (FESEM) and wear test was conducted by pin on disc wear tester. The experimental result revealed a lower specimen wear rate of the parameter is the frequency: 20 Hz, current density: 0.2 A/cm2 and duty cycle: 30 %. The ANOVA result revealed the pulse frequency and current density quadratic term are the most essential factor contributing 28.48, 29.95 % impact on wear resistance.

“…Nickel-based composite coatings are extensively used in a wide variety of industrial application owing to its improved magnetic [6], wear [7], electrical [8], corrosion [9], and frictions properties [10]. Nickel composites have embedded hard carbide particles and oxides particles such as SiC [11], Al 2 O 3 [12], WC [13,14], TiO 2 [15], SiO 2 [16] , DLC [17] and have showed promising tribological, thermal and mechanical properties, as well as good oxidation resistance. The composite coating properties can be improved by reinforcing the ceramic filler particles which are extremely beneficial for high temperature applications such as nuclear reactors, jet engines and electronic devices [18].…”

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.

In this paper, an investigation is reported on graphene platelet (GPL)/nickel (Ni) laminate coatings by electrochemical deposition. Nickel sulphamate baths with and without GPLs are used to produce GPL/Ni coatings with varied layers and pure Ni coatings for comparison. Microstructures, surface roughness, and mechanical performance of the coatings were examined. It is found that GPLs are homogeneously deposited in the Ni matrix. With the addition of GPLs, the surface roughness of the GPL/Ni composites increases while the average grain size of the Ni matrix decreases significantly. A higher hardness of coatings can be obtained by depositing more layers and introducing a higher content of GPLs. The microstructure of GPL/Ni composite coatings exhibits a preferred orientation at (111).
