“…A lower CoF after coating was also obtained and decreased by 9% and 6%, respectively. The fact that the samples coated with GNPs doped Al 2 O 3 showed a decrease of the average CoF compared with those before coating may be due to the friction‐reduction effect of GNPs in the coatings 4,16 . GNPs might be pulled out under the effect of thermal‐mechanical stress in the process of friction and wear and formed a film with self‐lubricating function at the friction interface.…”

“…Graphene has attracted more and more attention in the field of metal reinforcement and ceramic toughening. [4][5][6][7] Da et al 4 fabricated ceramic coatings reinforced with graphene using sol-gel method and tested their mechanical properties and tribological behavior at different temperatures. The experimental result showed that the hardness and fracture toughness of the coating were improved with the addition of graphene, and its wear rate was reduced.…”

This paper aims to experimentally investigate the effect of graphene nanoplatelets (GNPs) doped Al 2 O 3 coating deposited on the surface of cemented carbide substrate using suspension high velocity oxy fuel (SHVOF) thermal spraying technique. Scanning electron microscopy was applied to characterize GNPs doped Al 2 O 3 feedstock, the surface morphologies of cemented carbide before and after spraying, and the wear track morphology of cemented carbide after wear tests. The phases of GNPs doped Al 2 O 3 feedstock, uncoated and coated cemented carbide were analyzed by X-ray diffraction. The existence of GNPs was analyzed by Raman spectroscopy. A mixture of un-molten and molten splats formed on the surface of cemented carbide substrate after SHVOF thermal spray. The average coefficient of friction (CoF) of coated samples was slightly lower than that of uncoated samples, which might be due to the friction-reduction effect of GNPs. The wear rate of the samples was one order of magnitude higher than that of the alumina ball, showing that the wear of samples was the main wear between the friction couples. The wear mechanism of uncoated sample was mainly fatigue spalling, and that of cemented carbide substrate coated with GNPs doped Al 2 O 3 coating was mainly plowing and abrasive wear.

“…Nyquist and bode plots of galvanized steel (a) and pure E44 (b), SPAN/E44 (c), and G/SPANi/E44 (d) coated on galvanized steel immersed in 3.5% NaCl solution after different times SPAN/E44 (5.87 μF cm À2 ) after 144 h immersion. Moreover, the R c values of G/SPAN/E44 (19.4 kΩ cm 2 ) was much higher than that of the E44 (3.02 kΩ cm 2 ) and SPAN/E44(6.15 kΩ cm 2 ) after 144 h, which may be attributed to the good barrier and hydrophobic property of G 22,23. …”

In previous work, the corrosion performance and anti-corrosion mechanism of galvanized steel wire embedded in vegetation-growing concrete under marine environment was highlighted. In this work, a graphene-modified epoxy coating was developed and applied to the protection of galvanized steel in vegetation-growing concrete under a marine environment. The effect of dispersed graphene on the anticorrosion performance of the epoxy coatings was evaluated. The composite coatings displayed outstanding barrier properties against H 2 O molecules compared to the pure epoxy coating. Salt spray test results revealed superior corrosion resistance offered by the prepared graphene-modified epoxy coating on galvanized steel.

“…In this regard, solid self-lubrication (coatings, selflubricating materials), lubricants, or the superlubricity provide a versatile aisle for reducing the friction and wear of tribo-contacting components. The coatings, which are commonly prepared by spray methods, can serve as protective layers to reduce friction and wear loss of mechanical parts, such as plug rings and drilled holes [11][12][13]. Their simple preparation processes and low costs also accelerate their wide wear-critical applications [14].…”

In recent years, carbon nanomaterials such as fullerenes, carbon nanotubes, graphene, and nanodiamonds have been regarded as versatile triboproducts such as copper coins for various engineering/commerce-scaled applications. Their large-scale usages as ideal reinforcements for the key tribomaterials are motivated by their huge interfacial areas, unique physical/chemical characteristics, as well as multiple scale load-transferring mechanisms. Numerous investigators have kept on studying the possibilities of using carbon nanomaterials as solid lubricants, lubricating additives, or the superlubricated push hand. This review offers a comprehensive discussion of up-to-date survey in carbon nanomaterials for achieving the low friction and high wear resistant in the forms of coatings, bulk materials, lubricants; or even superlubric state in the tribosystems from nanoscale to macroscale. Finally, important conclusions, foreseeable challenges, and future outlooks for carbon nanomaterials are highlighted as the concluding remarks that are needed to impulse nanotechnology maturation and developments of tribological fields such as copper coin protections.
