## 1 Introduction
Therefore, improving the mechanical properties of Al alloys by adding reinforcing materials such as ceramics creates many difficulties through the working or machining of the synthesized nanocomposites. Therefore, ceramic additives must be introduced at a high accuracy of concentration to improve the mechanical and thermal characteristics of ANCs. Aluminum nanocomposites have been produced with many different methods, such as liquid-phase and solid-phase methods. Liquid-phase methods include casting and stir casting, while solid-phase methods include powder metallurgy [15]. Also, these processing methods involve many imperfections, like impurities, dislocations, brittle inclusions, and porosity, which make the ceramic nanoparticles heterogeneously dispersed in an aluminum alloy. At the same time, dislocations form in ANCs, perhaps owing to the differences in the thermal properties of aluminum and the additive nanoparticles [16]. These inclusions minimize wear resistance and strength, and in turn, diminish the performance of ANCs during the service. Moreover, the low wettability on the interfacial Al matrix and ceramic nanoparticles leads to diminished interface bindings between the Al matrix and the ceramic nanoparticles, hence limiting the usage of ANCs. AA6061 is an important alloy owing to its unique properties such as high strength, high resistance to corrosion and wear, low density, and high creep resistance. Therefore, this alloy can be used in various applicationsat elevated temperatures when reinforced by ceramic nanoparticles. The characteristics of ANCs are widely defined by the microstructure and chemical composition of aluminum alloys. The reinforcement additive materials are distinguished by their weight percentages and dispersion, which are extremely affected by the physical and mechanical properties, the cost of nanocomposites, and their performance [17]. The powder metallurgy technique is the best processing method to synthesize ANCs due to the easy-to-manufacture nanocomposites and it is suitable for producing different nanocomposites that cannot be produced in the liquid phase. On the other hand, it is used to produce nanocomposites with precision dimensions and can be used for many different alloys. Furthermore, it has good wettability at the interfaces between reinforcing nanoparticles and the Al matrix [18]. Many investigations have been made about Al alloys reinforced with ceramic nanoparticles. [PERSON] et al. prepared an Al/Al\({}_{2}\)O\({}_{3}\) composite material by powder technology. The effect of Al\({}_{2}\)O\({}_{3}\) and different sintering temperatures (550 \({}^{\circ}\)C and 650 \({}^{\circ}\)C) on the mechanical properties and wear characteristics of ANCs have been investigated. Al\({}_{2}\)O\({}_{3}\) has been incorporated by weight percentage at 20 wt.%. The results of this investigation show improvements in sintered density, micro-hardness, and wear resistance at 650 \({}^{\circ}\)C. This leads to strong interfacial bindings between Al\({}_{2}\)O\({}_{3}\) particles and the Al matrix. The images of the SEM examination show a uniform dispersion of Al\({}_{2}\)O\({}_{3}\) into the Al matrix [19]. [PERSON] and [PERSON] studied the mechanical characteristics of Al alloy reinforcing with SiCp nanoparticles manufactured by the powder technology method. The resultant data of this investigation show that SiCp particles are uniformly dispersed into the Al matrix with low porosities and enhance mechanical properties such as strength and micro-hardness [20]. [PERSON] et al. investigated the microstructure, wear characteristics and mechanical properties of Al/TiC composite manufacturing by friction stir processing (FSP). The obtained resultant data from this work show enhancements in wear and mechanical characteristics such as the strength and hardness of the fabricated composites [21]. [PERSON] et al. have studied the effect of graphite and SiC on the microstructure and mechanical characteristics of the hybrid nanocomposite.
