Abstract
The current investigation fabricated the hybrid and single nanocomposite matrices via the friction stir process technique (FSP). AA1060 is used as the base matrix, and Al2O3 and BN nanoparticles were selected as reinforcement additives. The microstructure, hardness, wear, and electrical properties were evaluated and investigated experimentally. The microstructure observation showed excellent grain refinement during FSP due to dynamic recrystallization action. Furthermore, homogeneous and good dispersion of the reinforcement nanoparticles on the composite surface. The electrical conductivity of the hybrid surface composite was noticed to have the lowest value compared to the other single composite additive and base matrix. The addition of BN and Al2O3 nanoparticles separately increases the composite matrix hardness (45-55%) compared to the base aluminum alloy. It has also been noted that the addition of BN and Al2O3 nanoparticles separately increases the composite matrix, but the hybridization of the two reinforcement results in better improvement. The BN nanoparticles significantly affected the physical and wear behavior of the hybrid and mono-composite of such reinforcement nanoparticles. Hence, all nanocomposites reinforced with BN nanoparticlesachieved lightweight and better wear resistance.
