“…It was due to the hardness of composites were improved and also graphene sheets acted as load bearing and solid lubrication components in the coating layer. Graphene Nano sheets behaved as a solid lubricant and reduced the plastic deformation by smearing on the worn materials substrate [15,27]. Thus, it made the composites worn out less.…”

“…In order to improve the wear resistance performance of nickel based composite coatings, it is necessary to find new and better reinforcements. It was proved that carbon materials, such as, graphite powder [9,10], CNTs [11,12] and especially graphene [13][14][15], are excellent strengthening materials for many composites and composite coatings.…”

Abstract. Graphene sheets and nickel powder were dispersed into Polyvinyl Alcohol (PVA) solution by magnetic stirring, and then pre-coating the mixed solution on the polished AISI4140 substrate. And after laser sintering, graphene nickel composite coating was successfully fabricated. Microstructures and composition of the composite coating before and after wear and friction experiments was studied by using Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM), Energy Dispersive Spectrometer (EDS) and Raman spectroscopy. Raman spectrum, SEM and TEM results proved that graphene sheets were dispersed in the composite coating. Nano indentation test results showed that graphene nickel composite coating had been greatly strengthened, and for pure nickel coating, the average friction coefficient was 0.35, while for the 10% graphene nickel coating, it was reduced to 0.13.

“…He et al deposited a self-lubricating Ni-P-MoS 2 composite coating on a mild steel substrate by electrodeposition, and it showed less wear and oxidation than the pure Ni-P coating [25]. Recently, graphene-based coatings have presented a great prospect of application to improve the friction and wear performance of the mating pair under low and moderate loads, but the friction performance did not reach the expected performance under high loads [26][27][28].Nano-powders of Cu and Sn alloy have been commonly used as lubricating oil additives to improve tribological properties for the advantages of low shear strength and good thermal conductivity. Kumar et al studied the friction and wear properties of CuSn alloy powders containing molybdenum sulfide under dry friction [29].…”

In order to investigate the friction and wear behavior between the nodular cast iron cylinder liner (Fe) and CuSn coated piston ring under heavy-duty conditions, piston rings with chromium(Cr) coating and CuSn-Cr coating were tested using the piston ring reciprocating liner test rig at the simulated working conditions of 56 MPa, 200 r/min, 190 • C. Compared with the Cr/Fe pair, the CuSn coating consumption of the CuSn-Cr/Fe pair made friction coefficient and cylinder wear loss decrease by 2.8% and 51.5%, respectively. Different size Sn patches worn from the CuSn coated piston ring were embedded into the cylinder liner surface based on the surface topography. This process was shown to reduce the surface roughness of a cylinder liner and form flatter plateau structures. Chemical elements analysis indicated that plateau structures on the cylinder liner surface matched with CuSn-Cr coated ring are helpful to promote the tribo-chemical reaction and generate the reactive products to protect the mutually contacted asperities.Although surface texturing on the cylinder liner or piston ring is an effective method to improve the wear behavior [7-9], various coatings prepared on the piston rings are also important means to improve heavy-duty friction and wear performance [10]. The CrN coating made by the physical vapor deposition or magnetron sputtering method has shown good high temperature resistance to adhesion [11][12][13][14]. In order to improve the thermal stability, oil compatibility, and internal stress of ceramic coatings, nanocomposite coatings (like TiN, TiAlN, TiSiN and TiSiCN) were developed to minimize the frictional losses and wear of piston rings in an automotive engine [15,16]. Shen et al. compared chromium-based ceramic composite (CKS) and nickel-chromium-molybdenum (NCM) coated rings sliding against cast iron liner and demonstrated that the anti-scuffing behavior of NCM is better than that of the CKS with the failure time as a criterion [17]. Wan et al. indicated that the presence of amorphous graphite-like carbon not only combated the scuffing damage and running instability effectively for conventional chromium-based coatings, but also improved the reliability and robustness of the piston rings [18]. Based on the increasing scuffing resistance experiments, diamond-like carbon (DLC) coated piston ring can protect the cast iron liner from scuffing up to 600 N normal load [19]. Its lower friction coefficient and wear loss were attributed to the formation of a mixed tribolayer [19][20][21]. But the existence of residual stress in the preparation process of DLC coating would cause the coating to crack. If stress concentration exerted on the contact interface was too high, it would lead to the coating wear or peeling [22].Compared with hard coatings, soft coatings have also attracted widespread attention for weakening the friction surface damage. Hamilton et al. investigated the relationship between macroscopic wear and the temperature of the MoS 2 coating [23]. Meng et al. indicated that the stabilized fricti...

Abstract-Graphene sheets and copper powder were dispersed into Polyvinyl Alcohol (PVA) solution by magnetic stirring, and then pre-coating the mixed solution on the polished AISI4140 substrate. Then laser cladding and laser remelting process were used to fabricated graphene copper and iron composite coating. Microstructures and composition of the composite coating was studied by using Scanning Electron Microscopy (SEM), Energy Dispersive Spectrometer (EDS) and Raman spectroscopy. Raman spectrum, SEM results proved that graphene sheets were dispersed in the composite coating. Vickers hardness test results showed that the composite coating had higher hardness values. With the graphene addition, the tribological performance of the composite coatings became better, and for pure copper iron coating, the average friction coefficient was 0.16, while for the 10% graphene copper iron coating, it was reduced to 0.13.
