“…Al 2 O 3 formation with high hardness is an important factor that guarantees the coatings to own favorable wear resistance [31]. The result shows that the phase composition of the coatings does not contain C peaks, which is consistent with previous works [18,32]. The probable reason is a small amount of graphene incorporated in the coatings [33].…”

The effect of added graphene concentration on the microstructure, phase composition, corrosion-and wear-resistance of plasma electrolyte oxidation (PEO) coatings formed on D16T aluminum alloy in silicate electrolyte with different concentrations of graphene were investigated. The results show that the morphologies of the coatings with graphene were obviously different ascribed to the mode of graphene incorporated into the coating. The coatings consisted of mainly α-Al 2 O 3 , γ-Al 2 O 3 , and Al, which were divided into an outer porous layer and a dense inner layer. The thickness of the coatings increased non-linearly with graphene concentration. The corrosion resistance of the coatings with graphene was significantly improved. The wear resistance of the coatings was also greatly improved apart from the coating with 3 g/L graphene. The coating produced in the electrolyte with 2 g/L graphene exhibited the optimal comprehensive properties because graphene successfully incorporated into the coating via the pores and spread on the surface of the coating.Coatings 2020, 10, 249 2 of 20 are influenced by various process parameters such as the constituent and concentration of electrolytes, oxidation time, substrate, various electrical parameters, and additives [7,8]. The constituent and concentration of the additive play an important role in changing the structure, morphology, wear-and corrosion-resistance of the coatings among those factors. A large number of works about the PEO coatings incorporated particles or powders like TiO 2 [9], ZrO 2 [10], Fe micrograins [11], α-Al 2 O 3 [8], and so on were performed. Zhao et al. [7] studied the effect of graphene oxide on the corrosion resistance of the PEO coating on AZ31 magnesium alloy, and reported that the incorporated graphene oxide markedly decreased micropores and improved the corrosion resistance of AZ31 magnesium alloy. Sarbishei et al. [12] reported that alumina nanoparticles incorporated into the PEO coatings formed on a titanium substrate, reducing the density of the coating and the pores' size. The corrosion resistance was improved with the increase of the alumina concentration, and the coatings formed in the electrolyte with 10 g/L alumina nanoparticles showed the best properties. Fatimah [13] studied the structure and corrosion properties of the coatings formed on 6061 Al alloy through the dual incorporation of SiO 2 and ZrO 2 nanoparticles into the oxide layer and found the coatings with SiO 2 and ZrO 2 displaying the best corrosion resistance because they were used as micropores blocker and cracks filler. Yazdanl et al. [14] studied the tribological performance of graphene/carbon nanotube hybrid reinforced Al 2 O 3 , and it was determined that the coating with graphene nanoplatelets hybrid reinforced Al 2 O 3 composites displayed the best wear resistance. Hvizdos et al. [15] studied the tribological properties of Si 3 N 4 -graphene nanocomposites, and Si 3 N 4 -graphene nanocomposites owned better wear resistance was also confirmed. Belmonte et al. [16] pro...

“…In addition, CNT-CBPC3 owes a larger real contact surface because of its smoother contact surface (as shown in the wear track of CNT-CBPC3), which resulting the lower internal stress in the same wear environment of CNT-CBPC3 than that of neat-CBPC0. 28,29 Corrosion protection performance of CBPCs.-To confirm the steady state and evaluate the corrosion resistance of the specimen, the open-circuit potential values of the uncoated mild steel (Q235), neat-CBPC0, CNT-CBPC1 and CNT-CBPC3 were measured before the potentiodynamic polarization and EIS measurements. As seen in Fig.…”

Chemically bonded phosphate ceramic coatings (CBPCs) with the addition of carbon nanotubes (CNTs) were prepared on mild steel (Q235) through the sol gel method. The wear and corrosion performance of CBPCs with the addition of CNTs were evaluated by tribological and electrochemical tests combining the analysis of microstructure, phase characterization, and curing behavior. Results indicate CNTs nanofiller significantly enhances the wear and corrosion behavior of CBPCs. The enhancement of wear performance for CBPCs with CNTs nanofiller is produced by the CNTs effectively hindering dislocation movement through the coating and substrate system and the occurrence of plastic deformation owing to their remarkable mechanical and lubricating properties. The enhancement of corrosion performance for CBPCs with CNTs nanofiller is due to the CNTs helping CBPCs to develop a denser and more compact microstructure, which contributes to prolonging the electrolyte diffusion path. In addition, CNTs exhibit excellent hydrophobicity and can absorb oxygen molecules, which prevents the corrosion process on the anode and cathode sections of coating and substrate system.

“…In the case of 2D-nanoller/ceramic systems, investigations revealed that the formation of a nanoller-containing tribolm was critical in achieving an observable reduction in the friction and wear of the coatings. 140,208 According to the report by Bian et al, 209 the wear volume and friction coefficient of chemically bonded phosphate ceramic coatings were signicantly reduced due to the introduction of graphene nanoplatelets (GNPs). According to the proposed wear mechanism, the graphene was extruded and adhered to the surface of the coating to form a lubrication lm.…”
