“…So far, various metals including stainless steel, 5 Au, 6 Pt, 7 Ag, 8 Ti, 9 and Cu 10 have been used to prepare Gr-metal composites by using different processes, such as power metallurgy, [11][12][13][14] the solgel method, [15][16][17] hydrothermal 18,19 and electrochemical deposition. [20][21][22] Among those processes, power metallurgy was the most frequently studied for producing the Cu-Gr composite, in which Gr is mixed with copper powders and composites obtained by hot pressing sintering. 23 The sol-gel method refers to a process in which Gr and metal alkoxide are dissolved into organic solvents to form a homogeneous solution, and then the other components are added for a reaction to form a gel at certain temperatures, and nally dry products.…”

“…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.…”

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.

“…Recently, the efficiency of the coating materials has been improved; the addition of carbon materials into the Ni-P electroless plating solution has been shown to lead to a coating material with good wear resistance, corrosion resistance, and anti-fouling. Wu et al [7] showed that an Ni-P-graphene oxide (Ni-P-GO) coating on a mild steel surface possessed the best anti-wear and microhardness properties when 40 mg/L of graphene oxide was added into an electroless plating solution. Matjie et al [8] prepared a modified diamond-like carbon (DLC) coating that reduced the adhesion of an aluminum the substrates were polished with a 600 grit waterproof abrasive paper and an 800 grit one to make the surface smooth and flat, respectively.…”

Biofouling on heat exchange devices can decrease heat transfer efficiency, corrode materials, and even lead to safety accidents. Most heat exchange devices are made of carbon steel that efficiently produces biofouling. However, in this paper, a nickel–phosphorus–reduced graphene oxide (Ni–P–rGO) coating was prepared on carbon steel by electroless plating to investigate the properties of iron bacteria biofouling. The surface coating was analyzed via scanning electron microscopy and Raman spectroscopy. After the carbon steel and the Ni–P–rGO coating were immersed into an iron bacteria solution for 120 h, the weight of the iron bacteria biofouling on the Ni–P–rGO coating sharply decreased when compared with the carbon steel. We can conclude that the concentration of graphene can affect the weight of iron bacteria biofouling. We also found that the coating solution with 40 mg/L of graphene performed the best in inhibiting biofouling by decreasing the weight of the biofouling by 97.2% compared to carbon steel.
