“…With different thermal expansion coefficients of the reinforcements and ADC and the soft nature of LG, the lubrication effect of the ADC-LG-hBN composites was increased, and, as a result, the CoF values of ADC-LG-hBN composites were reduced [73]. Thomas et al [74] reported similar behaviour in their literature. Therefore, adding LG and hBN reinforcements was beneficial in decreasing the wear rate and CoF of the ADC-LG-hBN hybrid composites, thereby increasing the overall service life.…”

In recent years, there has been increased interest in hybridizing metal matrix composites using agro-based-waste materials as sustainable choices. Despite the poor tribo-mechanical properties of conventional reinforcement materials, there is immense potential for using alternate reinforcing elements to enhance the mechanical features of matrix composite. In addition, conventional casting procedures present several challenges, including high costs and a lack of adequate mechanical qualities in the finished product. To combat these issues, the authors herein produce the well-known aluminium matrix composite (AMC), ADC 12 alloy, using waste Malabar lemon grass (MLG) ash at a fixed rate (6 wt%) and hexagonal Boron Nitride (hBN) at variable proportions (0, 1.5, 3, 4.5, and 6 wt%) as reinforcing element against traditional reinforcement particles to enhance the tribo-mechanical properties of casted hybrid AMC. In addition, the squeeze casting method produces the hybrid AMC, dramatically decreasing production costs and enhancing final product qualities. The hybrid AMC formed by squeeze casting is examined for its mechanical, corrosion, and tribological characteristics, with the findings indicating that the addition of MLG and hBN improved the mechanical, corrosion, and tribological properties of the ADC-MLG-hBN composites, with 6wt% MLG and 4.5wt% hBN reinforcements producing the optimal result. The experimental density of ADC-MLG- hBN composites was reduced by 8% when compared to the ADC 12 alloy, while the composites' tensile, hardness, and compressive strength were increased by 118.9%, 36.7%, and 33.6%, respectively. Similarly, the developed composite showed an improved corrosion resistance of 43.8% for 24 hours, and the wear rate decreased by 90.4%.

Taking advantage of the high specific surface area of the nanoparticles, boron nitride (BN) nanoparticles were incorporated into the semi-solidified aluminium-copper alloy Al–5Cu–Mn (ZL201) system during the casting process, and its properties and enhancement mechanism were studied. The results shown that the BN in the new composite material is more uniformly distributed in the second phase (Al2Cu), which can promote grain refinement and enhance the bonding with the aluminium-based interface, and the formation of stable phases such as AlB2, AlN, CuN, etc. makes the tensile strength and hardness of the material to be significantly improved (8.5%, 10.2%, respectively). The mechanism of the action of BN in Al2Cu was analyzed by establishing an atomic model and after calculation: BN can undergo strong adsorption on the surface of Al2Cu (0 0 1), and the adsorption energy is lower at the bridge sites on the two cut-off surfaces, which makes the binding of BN to the aluminum base more stable. The charge transfer between B, N and each atom of the matrix can promote the formation of strong covalent bonds Al–N, Cu–N and Al–B bonds, which can increase the dislocation density and hinder the grain boundary slip within the alloy.

“…This is often attributed to the reinforcing agents' increasing hardness, inversely affecting the wear rate according to Archard's law. It is worth noting that many researchers have suggested the benefits of reinforcing materials up to specific content, beyond which excessive addition may lead to severe wear [22][23][24]. In some cases, a brittle interface between the reinforcement and metallic matrix, such as Al 4 C 3 phase in an Al/SiC composite system, can result in an unsatisfactory wear response [25].…”

Aluminum matrix composites (AMCs) find extensive use across diverse industries such as automotive, aerospace, marine, and electronics, owing to their remarkable strength-to-weight ratio, corrosion resistance, and mechanical properties. However, their limited wear resistance poses a challenge for applications requiring high tribological performance. Abrasive wear emerges as the predominant form of wear encountered by AMCs in various industrial settings, prompting significant research efforts aimed at enhancing their wear resistance. Over the past decades, extensive research has investigated the influence of various reinforcements on the abrasive wear behavior of AMCs. This paper presents a comprehensive review of the impact of different variables on the wear and tribological response of aluminum composites. This review explores possible wear mechanisms across various tribosystems, providing examples drawn from the analysis of existing literature. Through detailed discussions on the effects of each variable, conclusions are drawn to offer insights into optimizing the wear performance of AMCs.
