“…The GO and Ti 3 AlC 2 could form continuous and compact transfer films on the wear surface, thus reducing the COF and wear rate. Zhang et al [ 67 ] fabricated SiC@GNSs by a wet ball milling process as fillers in alumina matrix composites, and the composites exhibited superior tribological properties because of the combined effect of graphene nanosheets (GNSs)-rich tribofilms, which improved the microstructure and mechanical properties of the composites. Similarly, SiC was coated in carbon nanotubes (CNT) to obtain SiC@CNT nanoparticles using a CVD method and mixed with Al6061 alloy to fabricate SiC@CNT/Al6061 composites via spark plasma sintering [ 68 ].…”

Owing to the diverse composition, adjustable performance, and synergistic effect among components, core–shell micro/nanoparticles have been widely applied in the field of tribology in recent years. The strong combination with the matrix and the good dispersion of reinforcing fillers in the composites could be achieved through the design of core–shell structural particles based on the reinforcing fillers. In addition, the performance of chemical mechanical polishing could be improved by optimizing the shell material coated on the abrasive surface. The physical and chemical state of the core–shell micro/nanoparticles played important effects on the friction and wear properties of materials. In this paper, the synthesis methods, the tribological applications (acted as solid/liquid lubricant additive, chemical mechanical polishing abrasives and basic units of lubricant matrix), and the functionary mechanisms of core–shell micro/nanoparticles were systematically reviewed, and the future development of core–shell micro/nanoparticles in tribology was also prospected.

“…Analysis of the literature shows that diverse nanoreinforcements were used to prepare alumina hybrid nanocomposite materials. This includes Al 2 O 3 -SiC-CNTs [32,40,41,43,133], Alumina-GNPs-SiC [39,134], Alumina-Graphene-CNTs [53,135], Alumina-modified multilayer graphene nanoplatelets [136], Al 2 O 3 –ZrO 2 -Graphene [137], Al 2 O 3 -SiCw-TiC [54,55], Al 2 O 3 -TiC-Ni [56], Al 2 O 3 -CNFs-SiC [57], and Alumina-Graphene based nanocomposites [58,59]. The majority of the performed studies were dedicated to the evaluation of mechanical properties and few researchers considered the tribological [54], electrical [40,54,58,59,60], and thermal properties [40,60].…”

“…Homogenous alumina hybrid nanocomposites that were reinforced by SiC-graphene nanosheets (GNSs) core-shell nanoparticles were prepared while using wet ball milling, ultra-sonicaton, and spark plasma sintering methods [134]. The well dispersed SiC-GNSs nanofillers, in the Al 2 O 3 matrix, led to small grain sizes, increased hardness, moderate improvement in fracture toughness, reduced coefficient of friction, and significant improvement in the electrical conductivity.…”

Although ceramics have many advantages when compared to metals in specific applications, they could be more widely applied if their low properties (fracture toughness, strength, and electrical and thermal conductivities) are improved. Reinforcing ceramics by two nano-phases that have different morphologies and/or properties, called the hybrid microstructure design, has been implemented to develop hybrid ceramic nanocomposites with tailored nanostructures, improved mechanical properties, and enhanced functionalities. The use of the novel spark plasma sintering (SPS) process allowed for the sintering of hybrid ceramic nanocomposite materials to maintain high relative density while also preserving the small grain size of the matrix. As a result, hybrid nanocomposite materials that have better mechanical and functional properties than those of either conventional composites or nanocomposites were produced. The development of hybrid ceramic nanocomposites is in its early stage and it is expected to continue attracting the interest of the scientific community. In the present paper, the progress made in the development of alumina hybrid nanocomposites, using spark plasma sintering, and their properties are reviewed. In addition, the current challenges and potential applications are highlighted. Finally, future prospects for developing alumina hybrid nanocomposites that have better performance are set.

“…Khun et al synthesized different microcapsules, such as wax @ silicone, wax @ poly(ureaformaldehyde) and hexamethylene diisocyanate @ poly(ureaformaldehyde) microcapsules, as lubricant additives to lower the friction and wear of the epoxy composites [27][28][29][30] . Zhang et al incorporated core-shell SiC@graphene nanosheets (GNSs) nanoparticles into alumina matrix composites, and found that the GNSs-rich tribofilms conduced to reduce the COF and wear rate of the composites [31] . Chen et al prepared carbon nanofiber (CNF) @ molybdenum disulfide (MoS 2 ) core-shell structure hybrid as lubricants in epoxy, and proposed that the synergy effect between CNF and MoS 2 make them form dense and uniform lubricating films under reciprocating stress [32] .…”

The tribological behaviors of core‐shell n‐octadecane@TiO₂/epoxy composites

et al. 2020

In this work, the n-octadecane@TiO 2 particles with core-shell structure were successfully prepared via a sol-gel method in an oil-in-water (o/w) emulsion. The resultant core-shell particles were incorporated into epoxy matrix to prepare composites. Compared with pure epoxy and TiO 2 doped epoxy, the incorporation of n-octadecane@TiO 2 reduced the friction coefficient (COF) and wear rate of epoxy. According to the systematical investigation of the wear tracks on three samples and scars on their friction antithesis balls, it was speculated that the antifriction effect of core-shell additives on composites were mainly attributed to the mixture formed by the crushed n-octadecane@TiO 2. The mixture not only backfilled the tearing-like cracks on worn face generated by fatigue wear, but also promoted the formation of transfer film.
