Mechanical and tribological properties of self-lubricating metal matrix nanocomposites reinforced by carbon nanotubes (CNTs) and graphene – A review

“…The very high value of the surface tension of molten aluminum compared to carbon nanotubes makes synthesis of aluminum matrix composite reinforced with carbonaceous materials a challenging task. One of typical way to improve wetting behavior of molten aluminum on carbonous materials is by forming metallic coatings, such as copper and nickel on reinforcements to reduce its contact angle, as shown in Figure 3 [86,87]. The formation of Al 3 Ni, Al 3 Ni 2 and CuAl 2 as an intermetallic compound plays a key role in achieving good wettability between aluminum with copper and nickel [28,88].…”

Influences of graphite reinforcement on the tribological properties of self-lubricating aluminum matrix composites for green tribology, sustainability, and energy efficiency—a review

“…This will lead to a reduction in surface energy of the reinforcement and hence a better wettability of particles by the molten metal. The other methods available to improve the wettability of the reinforcements are activating the reinforcement particles by preheating to a certain temperature [5] and coating of reinforcement particles using appropriate coatings, such as copper and nickel [108,109] as shown in Fig. 4.…”

Carbon Materials Reinforced Aluminum Composites: A Review

“…Liu et al [37] improved the TC of short carbon fibers/Al composites from 117 to 208 W m -1 K -1 by using Cu coating. Coating processes of Cu on VGCFs were studied by some researchers [36], and Cu-coated VGCFs were successfully used to improve the mechanical properties of aluminum alloys [125,126]. However, in Cu-coated C/Al composites, intermetallic compounds such as CuAl 2 formed near the interface would reduce the properties of the composites [29,58], as shown in Fig.…”
