“…Recent research has reported that metal matrix composites with aluminum have exhibited low density and the ability to strengthen the material by precipitation, corrosion resistivity, thermal stability, and high electrical conductivity for potential tribological applications in the automotive and aerospace industries [1,2]. It was found that inserting ceramic particles such as graphite, silicon carbide, aluminum oxide, and titanium carbide improved the noticeable tribological and mechanical properties of AMMCs [3][4][5][6][7].…”

In recent times, tribological properties are gaining and grabbing great attention in metal matrix composites. They can provide significant benefits such as a lower coefficient of friction, wear resistance, high strength, and stiffness. Considering all these parameters, this research article mainly focuses on developing an aluminum hybrid nanocomposite material fabricated by powder metallurgy. Then, the results were examined using a pin-on-disk apparatus. Further optimization techniques such as the Taguchi approach under Design of Experiments have been adopted to obtain a minimal outcome of various assumed parameters such as A. percentage weight fraction of graphite content (Gr), B. the sliding distance, C. the sliding speed, and D. the stress applied. In addition, we have chosen parameters such as friction and wear loss for optimizing the outcome, including the main effect plots for the S-N ratio and the Analysis of Variance (ANOVA) approach. Based on the experimental results, we have noticed that friction and wear loss coefficient increase with increased applied load and sliding distance. Also, it was noted that there was a slight decrease in the coefficient of friction and wear loss when an increment was made in the graphite content, respectively. It was perceived that the sample containing 10% of graphite (Gr) could create a self-lubricating effect that significantly reduced wear loss and the coefficient of friction. Finally, by considering all these achieved results, aluminum nanocomposites can be employed in automobile, defense, and aerospace applications as they can reduce the weight of the components with improved wear behavior and more thermal stability.

“…Recent works of Edoziuno et al 33 and Aigbodion and Ezema 34 have been limited to using PKS and PKSA nanoparticles as a single reinforcing particulate in the matrix for AMCs production. The tribological and physical properties of Al/SiC/PKSA have been previously published by Ikubanni et al 8 Recently, Ikubanni et al 35 reported the corrosion behavior of hybrid AMCs produced using SiC and PKSA as reinforcing particulates in 3.5% NaCl environment. Hence, there is a need to gather more information on the effects of utilizing PKSA and SiC as supporting particulates and how the incorporation in matrix alloy would affect the corrosion susceptibility of the composites.…”

“…5 Composite materials in advanced material development can be categorized based on their matrices, such as metal composites, polymer composites, and fiber composites, as recorded by research scientists. [6][7][8][9] Aluminium is the principal metal that has been extensively utilized as a matrix due to its excellent physical and mechanical properties, such as good weight-to-strength ratio, good wear resistance, toughness, high specific strength, and so on. 8,10,11 When Al matrix is reinforced with a single ceramic reinforcement, they are called monolithic composites.…”

The recycling of agro‐waste as complementary reinforcements has received significant recognition in the development of aluminium matrix composites. Hence, this study examines the corrosion behavior of Al6063 reinforced with hybrid SiC/PKSA (palm kernel shell ash) particles. Through various ratios of SiC and PKSA particles in Al6063 alloy, composites were fabricated by double stir casting. Samples were cut and metallographically prepared for 1 M H2SO4 solution corrosion experiments. Gravimetric, potentiodynamic polarization and electrochemical impedance spectroscopic analyses were employed. The composites corroded initially at relatively high rates, gradually declining during long immersion times in the acidic solution. The intersection of reinforcements at the general surfaces of the composites where flawed oxide skins predominate acted as active sites for corrosion initiation. From potentiodynamic polarization studies, the corrosion currents increased with time for all specimens, with A9 being 1075.65 μA/cm2 at 72 h as against 857.99 μA/cm2 at 24 h of measurement. The corrosion potentials for all the specimens hovered around −654.00 to −647.22 mV. Bode plots revealed similar electrochemical reactions over all the substrates' surfaces. The relative corrosion resistance by the specimen depends on the oxide films' nature as the cathodic interfacial reinforcements dropped off into the acidic environment.

“…So, it has been found that a decrease in hard particles or an increase in ES could affect sliding wear [25]. According to Ikubanni et al [26], hybrid-reinforced AMCs were explored by using Al6063 alloy, SiC, and palm kernel shell ash (PKSA) reinforcements. With the use of the double stir casting process, different amounts of SiC and PKSA were incorporated into the matrix metal at various ratios.…”

Al6061 alloy is most commonly used in automotive, marine, and aerospace applications to lighten the composite and increase its strength. Al6061 alloy is a precipitation-hardened aluminum alloy used as a matrix material. Beef bone is a biowaste that has polluted the environment and the people who live in the vicinity of its manufacturing and disposal sites. Biowaste has been used in a variety of ways by researchers in recent years, including activated carbon, water purification, reinforcement in composites, fillers, additives, etc. Beef bones that had been abandoned as waste were collected, cleaned, and grounded into a fine powder with a particle size of 50–100 nm and used as reinforcement. Squeeze casting process is used to create the newly created aluminum composite (Al6061 + 0%, 5%, 10% of bone powder). The aluminum composite was fabricated and three samples were successfully obtained for further testing and analysis. The prepared Al composites with nanopowder reinforcement are analyzed for surface morphology, elemental identification, hardness, porosity, tensile strength, and compression strength. The percentage of porosity in the composite is improved by 36.7% when compared to the Al6061 alloy. Similarly, the tensile strength of the produced composite is increased to 5.59%. A significant improvement is observed in the wear resistance and hardness of the composite as 54.55% and 48.65%, respectively.
