“…Applications of aluminum alloys in the automotive and aerospace industries have been developed with respect to reducing fuel usage and shielding the environment, where they can successfully replace steel and cast iron parts [32], such as brake drums, cylinder liners, cylinder blocks, and drive shafts, in order to reduce fuel and help the environment [16]. However, low mechanical properties and tribological behavior of aluminum alloys are disadvantages, and hence, it can be resolved by embedding ceramic particles, such as Al 2 O 3 [33], silicon carbide (SiC) [34], BN [35], B 4 C [36], TiB 2 [37], and carbonous materials depending on their applications. An aluminum composite fabricated by embedding ceramic particles in its matrix possesses an attractive combination of physical and mechanical properties, which in monolithic aluminum alloys cannot be obtained normally.…”

Aluminum/graphite (Al/Gr) composites have been used as self-lubricating materials due to the superior lubricating effect of graphite during sliding. This paper summarizes various tribological aspects of self-lubricating aluminum composites. The influence of various factors such as (a) material factors, graphite size and volume fraction, and (b) mechanical factors, applied load and sliding speed on the tribological properties of self-lubricating aluminum composites, is discussed. Furthermore, the tribological properties of selflubricating composites as a function of these parameters and the active wear mechanism involved in various systems are discussed. Bringing self-lubricating composites into different operating systems is a solution to reduce the use of external toxic petroleum-based lubricants in sliding contacts in a way to help the environment and reduce energy dissipation in industrial components for strategies toward sustainability and energy efficiency.

“…The addition of hard ceramic reinforcements such as SiC, Al 2 O 3 , B 4 C, TiB 2 , and MoS 2 to the Al matrix may adversely influence the wear properties of the resultant composites [20][21][22][23][24]. The major limitation of ceramic reinforcements is that they increase the hardness of the composites.…”

Improvement in surface properties and retainment of bulk properties are essential requirements for the design of components for wear resistance applications. This paper summarizes various features of Al/SiC/Gr hybrid composites that can be employed in different tribological applications. The study has revealed that the processing route plays a significant role in obtaining a homogeneous structure of these composites. In powder metallurgy, the selection of sizes of the matrix and reinforcement powders is crucial, whereas the wettability between the reinforcement particles and molten alloy is a major challenge in liquid metallurgy. The incorporation of SiC particles increases the mechanical strength and wear performance of Al composites. However, ejection of these particles can reduce the wear performance of Al composites under severe conditions. The addition of Gr particles helps in the formation of a thick and extensive tribolayer on the wear surface. This layer reduces direct contact between the rubbing surfaces, thereby decreasing the wear rate under certain conditions. Morphological analysis of worn surfaces has confirmed that the hybrid composites exhibit superior wear properties than the pure Al alloy and the ceramic-reinforced composite. However, increase in the Gr content beyond a limiting value can deteriorate the tribological properties of these composites. Therefore, true optimization of a tribosystem (of the hybrid composite and counterface) can be achieved by selecting appropriate reinforcement contents.

“…The wear properties of Al framework may antagonistically be influenced by the addition of hard ceramic reinforcements such as SiC, Al 2 O 3 , B 4 C, TiB 2 , and MoS 2 [21][22][23][24][25]. As the including of ceramic reinforcement enhances the hardness of the composites, this makes it unsatisfactory for some of the applications.…”

AA7075 is a combination with zinc as an essential alloying component. When contrasted with numerous different steels its quality is very similar. It has greater fatigue strength, however less protection from corrosion than numerous other Al alloy. This paper investigates the possibility of growing elite composites with low cast, for different applications like aviation and automobile. The impact of different reinforcements on the AA7075 based composite has been investigated. The mechanical properties, have been seen to be either practically identical or better after heat treatment to the as cast composites. It has been found from the past research that the nearness of the hard ceramic stage, for example, SiC, TiB 2 , B 4 C, Al 2 O 3 effects directstrengthening of the composites. In view of the information from the previous research, the application region of AA7075 AMCs has been shown in the present review. It has been gathered that the hybrid composites give greater reliability and flexibility in the design of components depending upon the reinforcement and matrix material.
