“…The maximum weight percentage (15 wt%) was the major reason to enhance the better wear resistance and lesser coefficient of friction. It is revealed that the maximum frictional heat was generated between the specimen and counter disk, so that the heat was not increased on the specified composites by the presence of nano boron carbide particles [20][21][22][23][24][25]. The presence of nanosized boron carbide was a major aspect to improve their wear rates and similarly, the lesser setting temperature was another reason to reduce the wear tracks.…”

The aluminum metal matrix composites were broadly exploited in the applications of automotive, aerospace, and other defense with functionally graded materials-related application. Above applications definitely required excellent mechanical characteristics. Therefore, in this way, the major attempt was made on the nano-based composites with aluminum alloy utilization. In this research, aluminum alloy AA8011 and the ceramic-based reinforcement particles of nano boron carbide (B4C) were selected for producing the metal matrix composites by the liquefying process or stir casting route. The weight percentage of nano boron carbide particles having 15 wt% was subjected to add into the aluminum alloy during the stir casting process. Then, processed nano boron carbide and AA8011 specimens were prepared to conduct tribological behaviors with various processing conditions like sliding velocity, setting wear temperature, and applied load by the tribometer setup. The scanning electron microscope was employed to examine the processed composites samples and worn-out surface samples. Finally, the multiobjective optimization was used to measure the individual performances of the tribological parameters by the gray relational technique.

“…1 A good selection of the reinforcement phase and the fabrication methodology is necessary for MMC's to have their ideal properties and improved performance. 2 Magnesium (Mg) is the eighth most common element in the universe. It has a density of 1.74 g/cm 3 , which is about the same as two-thirds the density of aluminum, onequarter the density of zinc, and one-fifth of steel.…”

“…The XRD results ensured the presence of the reinforcement in composites and the development of intermetallic phases, proving that matrix reinforcement materials are thermally stable. The tribo characteristics of the materials were investigated against a various load (7.5, 15, 22.5, and 30 N), frequency (2,4,6, and 8 Hz), and temperature (50°C, 100°C, 150°C, and 200°C) conditions using a linear reciprocating tribometer at the constant sliding distance of 200 mm and the stroke length of 10 mm. The SEM was used to analyze the worn surfaces of alloy, composite, and hybrid composites at ambient and increased temperatures.…”

The influence of TiN hard ceramic concentration and coordination effect of hBN solid lubricant particulates on reciprocating wear and friction behavior of AZ91D alloy-based magnesium matrix composites is investigated in this work. A unique stir-ultrasonication-squeeze casting procedure was employed to fabricate the composites. The fine dispersion of reinforcing particulates in matrix was examined using Optical Microscopy (OM) and Scanning Electron Microscopy (SEM). The X Ray Diffraction (XRD) analysis confirmed the existence of reinforcements in composites and formation of intermetallic phases demonstrating the thermal stability of matrix reinforcement materials. The hardness of fabricated AZ91D/5 wt.% TiN (AT), AZ91D/5 wt.% hBN (AH), AZ91D/5 wt.% TiN/5 wt.% hBN (ATH), and AZ91D/10 wt.% TiN/5 wt.% hBN (ATTH) composites were increased by 18.37%, 8.14%, 11.68%, and 25.2% in comparison with as-cast alloy “A”. The tribo-properties of single and dual ceramic particles reinforced materials were investigated using a linear reciprocating tribometer at an unchanged sliding distance of 200 mm and stroke length of 10 mm under varied loads (7.5, 15, 22.5, and 30 N), reciprocating frequencies (2, 4, 6, and 8 Hz), and temperature conditions (50°C, 100°C, 150°C, and 200°C). Compared to material “A,”“ATTH” composite performs well in terms of wear behavior, with performance increasing by 42.63% and 54.33% respectively, under ambient and enhanced conditions. At low load, increased frequency accelerates material removal from the plate’s surface due to direct abrasion and plowing action caused by rough asperities on the counterface. The increase in applied load under high-frequency settings increases the pin’s contact pressure with the sample surface, which raises the temperature and causes the shallow grooves to severe delamination. At increased temperatures, the wear characteristics of intense oxidation, plastic deformation, and significant delamination were discovered on manufactured materials.

Because of its improved formability, lower production costs, and mechanical properties, aluminum metal matrix composite is the highly intriguing engineering material. It can meet the needs of modern engineering applications used in the automotive, military, aerospace, and marine industries. Hybridization of reinforcement is adopted to develop tailor‐made properties of composites for specific application. In this study, Al‐B4C‐Gr hybrid composites were produced with varying graphene content (0.25, 0.50, 0.75, and 1 wt.%) and keeping boron carbide (10 wt.%) as constant, the effect of graphene proportion on the mechanical properties of produced composites was evaluated. It has been observed that increasing the Gr reinforcement particles in the synthesized composites improves the mechanical characteristics of the composites, such as raising the tensile strength to 215 Mpa and the hardness to 110 HV due to the presence and proper distribution of reinforcement in the matrix. When compared to the base alloy, the tensile strength and hardness of Al10B4C0.75Gr composites rose by 27.174% and 67.290%, respectively. The dry sliding wear behavior of Al‐10 wt.% B4C‐wt.%Gr hybrid composites confirms that graphene and B4C particles in the matrix increase the wear resistance of the produced MMCs. The each parameter such as sliding distance, sliding velocity and load has its influence toward the better wear resistance of the developed composites and were discussed.
