“…Hence, it is expected that the presence of wear debris shown in Figure 19b is due to the absence of h-BN. Lastly, wear debris in Figure 19d which are related to AA6082 and AA6082/h-BN particles is originated from material removal in the adhesive mechanism, which was much lower in the presence of TiB 2 , as well as the abrasive mechanism [158]. Importantly, presence of TiB 2 and h-BN in the wear interface can altered the wear mechanism from adhesive to abrasive [156].…”

“…Figure 19f illustrates the worn surface of neat Ni3Al containing large debris, while the finer particles in debris on the worn surface of the composite can be seen, causing a lower wear rate [156]. In another research, the high temperature tribological properties of Ni-based self-lubricating coatings deposited by atmospheric plasma sprayed coating were studied [158]. The outcomes displayed that the COF and wear rate of the samples containing 5 wt.% and 10 wt.% of h-BN decrease when the temperatures Tribological behavior of BN nano-platelet (BNNP) reinforced Ni 3 Al intermetallic matrix composite has also been researched [159].…”

Ever-increasing significance of composite materials with high thermal conductivity, low thermal expansion coefficient and high optical bandgap over the last decade, have proved their indispensable roles in a wide range of applications. Hexagonal boron nitride (h-BN), a layered material having a high thermal conductivity along the planes and the band gap of 5.9 eV, has always been a promising candidate to provide superior heat transfer with minimal phonon scattering through the system. Hence, extensive researches have been devoted to improving the thermal conductivity of different matrices by using h-BN fillers. Apart from that, lubrication property of h-BN has also been extensively researched, demonstrating the effectivity of this layered structure in reduction of friction coefficient, increasing wear resistance and cost-effectivity of the process. Herein, an in-depth discussion of thermal and tribological properties of the reinforced composite by h-BN will be provided, focusing on the recent progress and future trends.

“…And the strong collision between TiB 2 hard particles and substrate generates fragmentation leads to the decrease in grain size of TiB 2 hard particles. The grain refining action of TiB 2 particles can further be considered to play a role in lowering the wear rate [16]. Thirdly, the TiB 2 -Ni coatings have higher hardness than that of substrate and have dense microstructure with low porosity or without obvious cracks; therefore, the coatings have an intrinsically superior resistance to abrasion.…”

TiB 2 -Ni coatings with different binder phase contents were sprayed on Q235 substrate by a high-velocity oxygen-fuel (HVOF) method using ball-milled powders. The microstructure, phase compositions, as well as thermal shock behavior, abrasive wear, and corrosion resistance to molten Al-12.07 wt%Si alloy performances of as-sprayed coatings were investigated. The results show that the three TiB 2 -Ni coatings structure is dense with low porosity, and the main phase compositions of the coatings are TiB 2 and Ni similar to those of original powder. The coatings that have superior performance of thermal shock resistance have good bond to the substrate with no change in thickness and microstructure of coatings. Meanwhile, the coatings also have good durability in the molten Al-12.07 wt%Si after 60-h immersion test. And the mass loss of Q235 steel is five times as much as that of TiB 2 -50Ni coatings after abrasive wear test.

“…The wear behavior of the particle reinforced Al matrix composites at elevated temperatures is one of the major concerns for elevated temperature applications. The high-temperature wear behaviors of micro-sized particle reinforced metal matrix composites (microcomposites) have been reported in the literature [ 5 , 11 , 12 ]. Natarajan et al [ 11 ] showed that the relative wear resistance of the 5.0 micro-sized TiB 2 /6063 composite fabricated by the flux assisted synthesis approach was 9.0% higher than that of the matrix alloy in dry sliding wear tests at 200 °C under 9.8 N applied load.…”

Nano-sized ceramic particle reinforced aluminum composites exhibit excellent room-temperature mechanical properties. However, there is limited research on the dry sliding wear behavior of those composites at elevated temperatures, which should be one of the major concerns on elevated temperature applications. Here the Al-Cu composites reinforced with nano-sized TiCp were fabricated. The dry sliding wear behaviors of the nano-sized TiCp/Al-Cu composites at various temperatures (140–220 °C) and loads (10–40 N) with different TiCp contents were studied, and the results showed that the nanocomposites exhibited superior wear resistance. For instance, the relative wear resistance of the 0.5 wt.% nano-sized TiCp/Al-Cu composite was 83.5% higher than that of the Al-Cu matrix alloy at 180 °C under 20 N, and was also 16.5% higher than that of the 5 wt.% micro-sized TiCp/Al-Cu composite, attributed to the pronounced Orowan strengthening effect of nanoparticles. The wear rates of the nanocomposites were always lower than those of the Al-Cu matrix alloy under the same test condition, which increased with the increase in temperature and load and with the decrease in TiCp content.
