“…This lowering of the wear rate and the coefficient of friction was observed due to formation of a mechanically mixed layer during sliding, and such a layer acted as a solid lubricant film and protected the surfaces. B4C-AA6061 composites were fabricated by ultrasonic-assisted casting [188] and, where the friction and wear were measured; AA6061 reinforced with 1.5 vol% of nano B4C particle had lower weight loss (136% lesser than the unreinforced AA6061 alloy) possibly due to the improved hardness by the uniform distribution of nanoparticles that served as load-bearing elements in the matrix. Zinc-aluminum (ZA) cast alloys, known for good castability and high wear resistance, have been reinforced with nano-sized Al2O3 particles using ultrasonic-assisted stir casting [189].…”

Lightweight high-strength metal matrix nano-composites (MMNCs) can be used in a wide variety of applications, e.g., aerospace, automotive, and biomedical engineering, owing to their sustainability, increased specific strength/stiffness, enhanced elevated temperature strength, improved wear, or corrosion resistance. A metallic matrix, commonly comprising of light aluminum or magnesium alloys, can be significantly strengthened even by very low weight fractions (~1 wt%) of well-dispersed nanoparticles. This review discusses the recent advancements in the fabrication of metal matrix nanocomposites starting with manufacturing routes and different nanoparticles, intricacies of the underlying physics, and the mechanisms of particle dispersion in a particle-metal composite system. Thereafter, the microstructural influences of the nanoparticles on the composite system are outlined and the theory of the strengthening mechanisms is also explained. Finally, microstructural, mechanical, and tribological properties of the selected MMNCs are discussed as well.

“…This showed improved dispersion and betterment in mechanical properties. Poovazhagan et al [23] have dealt with ultrasonic cavitation technique for degassing and improved dispersion of reinforcement in melt. This technique further helped in reducing the agglomeration when nano-sized particles are used as reinforcement [24].…”

The Metal Matrix Composites (MMCs) are increasingly replacing the commercial alloys in engineering components and undergoing intense analysis in the development of advanced composite structures. The metal matrix composites exhibit superior mechanical and tribological behavior than alloys in wear critical applications. Profound research works have been carried out in manufacturing the MMCs for improved friction and wear behavior. This study highlights the recent investigations from the perspective of wear behavior of MMCs. The effect of reinforcements and manufacturing processes of composites on wear behavior is elaborated. The significance of mechanical factors such as normal load, sliding speed and sliding distance is explained. The wear mechanisms observed in MMCs and studies on sub surface damages of composites are reported.

Aluminum matrix composites (AMCs) demonstrating a good combination of properties that are hard to acquire by a monolithic aluminum material. Since the last few decades, investigators have shown their keen interest to advance these materials for complex applications. Homogeneous reinforcement distribution, defect-free microstructure, and improved resultant properties depends on the fabrication method along with matrix and reinforcement materials and size. Two-step melt stirring technique and K2TiF6 flux enhanced the wettability and improve the particle distribution of boron carbide (B4C) in AMCs. The mechanical properties of the AMCs were enriched by either extrusion process or thermal treatment. Hybrid composites exhibited better characteristics than mono composites. Surface composites manufactured by incorporation of reinforcement in the surface layer; offer good surface properties without losing toughness and ductility. The B4C-Al interfacial reactions produce different precipitates in AMCs and damaged the composite's age-hardening ability. B4C reinforced friction stir processed surface composites exhibits refined structure and better properties compared to the aluminum matrix. The strength, hardness, and wear resistance of AMCs increased with rising fraction and reducing the size of B4C up to a certain level. Wear rate increases with rising applied load, sliding time and speed. A review of effect of B4C reinforcement on different properties of mono and hybrid AMCs with summarized results attained and concluded by different investigators is presented in this paper to help researchers in the field. At the end of this paper a position given to conclusions and future directions.
