“…The tribological results revealed that the GO particles improved the friction and wear resistance through the formation of a tribolayer at the contact interface [117]. Studies on Ni-graphene composite coatings showed that COFs of the composite coatings were reduced by increasing the amount of graphene reinforcement which caused improvement in wear resistance properties (Figure 7) [105], [106]. According to the research done by J. Chen et al [105], the friction coefficient decreased with the increased amount of graphene.…”

“…Studies on Ni-graphene composite coatings showed that COFs of the composite coatings were reduced by increasing the amount of graphene reinforcement which caused improvement in wear resistance properties (Figure 7) [105], [106]. According to the research done by J. Chen et al [105], the friction coefficient decreased with the increased amount of graphene. The friction coefficients shown by the coatings containing 0.1 g⸳L -1 and 0.2 g⸳L -1 graphene were higher than the COF of pure Ni coating (0.7), and for the coating having 0.3 g⸱l -1 graphene was nearly the same as pure Ni coating.…”

“…This increase in hardness can be due to the finer grain size of Ni/Graphene composite compared to Ni coating, which causes hindrance to the movement of the dislocations and led to plastic flow resistance and enhanced hardness. The high mechanical strength of graphene may have played a role in the hardness improvement in the composite coating [105]. Furthermore, the mechanical properties of the Ni matrix improved based on the formation of Ni crystalline in its plane (111), facilitated by graphene [106].…”

“…Thus, the addition of graphene should be more than 0.3 g⸳L -1 to be effective in reducing friction. This can be due to the high Young's modulus of graphene hindering the formation of a lubricating film when the amount of graphene is less [57], [105]. Tribological analysis of electrodeposited pure cobalt and cobalt/graphene composite coatings on St37 steel substrates revealed that the co-deposition of graphene particles decreased the volume loss and the friction coefficient of a pure cobalt coating [119].…”

Graphene derivatives reinforced metal matrix nanocomposite coatings: A review

Due to the extraordinary mechanical, thermal, and electrical properties of graphene, graphene oxide (GO), and reduced graphene oxide (rGO), these materials have the potential to become ideal nanofillers in the electrodeposited nanocomposite coatings. This article provides an overview of literature on the improvements of properties associated with graphene, GO, and rGO-reinforced coatings, along with the processing parameters and mechanisms that would lead to these improvements in electrodeposited metal matrix nanocomposite coatings, where those affected the microstructural, mechanical, tribological, and anti-corrosion characteristics of coatings. The challenges associated with the electroplating of nanocomposite coatings are addressed. The results of this survey indicated that adding graphene into the plating bath led to a finer crystalline size in the composite coating due to increasing the potential development of specific crystalline planes and the number of heterogeneous nucleation sites. This consequently caused an improvement in hardness and in tribological properties of the electrodeposited coating. In graphene reinforced metallic composites, the severe adhesive wear mechanism for pure metallic coatings was replaced by abrasive wear and slight adhesive wear, where the formation of a tribolayer at the contact surface increased the wear resistance and decreased friction coefficient. Furthermore, superhydrophobicity and smaller grain size resulted from embedding graphene in the coating. It also provided a smaller cathode/anode surface ratio against localized corrosion, which has been found to be the main anti-corrosion mechanism for graphene/metal coating. Lastly, the study offers a discussion of the areas of research that need further attention to make these high-performance nanocomposite coatings more suitable for industrial applications.

“…The properties of these materials can be controlled through process parameters, such as bath composition, deposition current density, and bath temperature. Studies have investigated various materials for reinforcing phases, incorporated into the metal matrix, such as oxides [ 1 , 2 , 3 ], nitrides [ 4 , 5 ], carbides [ 6 , 7 , 8 ], sulfides [ 9 ], metals [ 10 , 11 ], and carbon allotropes [ 12 , 13 , 14 , 15 ]. When embedded in the metal matrix, nanoparticles improve mechanical, tribological, or corrosion properties.…”

This article presents Cu/diamond composite coatings produced by electrochemical reduction on steel substrates and a comparison of these coatings with a copper coating without diamond nanoparticles (<10 nm). Deposition was carried out using multicomponent electrolyte solutions at a current density of 3 A/dm2 and magnetic stirring speed of 100 rpm. Composite coatings were deposited from baths with different diamond concentrations (4, 6, 8, 10 g/dm3). This study presents the surface morphology and structure of the produced coatings. The surface roughness, coating thickness (XRF), mechanical properties (DSI), and adhesion of coatings to substrates (scratch tests) were also characterized. The coatings were also tested to assess their solderability, including their spreadability, wettability of the solder, durability of solder-coating bonds, and a microstructure study.
