The stir-casting method was employed to study the effect of adding silicon carbide and the bamboo leaf ash into the Al-4.5wt.%Cu alloy. The standard procedure was followed in analysing the mechanical behaviour of the fabricated composites on parameters such as density, tensile strength, and hardness. Optical microscope, scanning electron microscope with energy dispersive analysis of X-rays, and X-ray diffraction analysis helped in studying the microstructure of the composites. The study reveals that the reinforcement particles in the matrix alloy were distributed nearly homogeneously, and with a clear interface. The X-ray diffraction patterns indicate the presence of silicon carbide and bamboo leaf ash without an intermetallic reaction. The density of the hybrid composites reduces with the addition of bamboo leaf ash, but porosity increases. The fabricated composites gain in tensile strength and hardness as the reinforcement particles are added, but elongation was decreased.

“…Also, the reinforcement particles protect the softer matrix. The hard reinforced particles thus restrict deformation and resist indentation when touched [28]. The increased hardness may also be because SiC and BLA withstand the major load transferred by the matrix.…”

“…Soorya Prakash et al [ 54 ] stated that the inclusion of rock dust particles to the AA6061 alloy enriched the wear protection of the AAMCs. Moses et al [ 55 ] observed that the wear resistance of the AAMCs was enhanced with an increase in the weight percentage of TiCp. Also, the hard TiC contents include the plain matrix, which helps to decrease the PD affected by the improved wear resistance of the composite.…”

In the current research, AA6082 aluminium alloy matrix composites (AAMCs) incorporated with various weight fractions of titanium diboride (0, 3, 6, and 9 wt%) were prepared via an in situ casting technique. The exothermic reaction between inorganic powders like dipotassium hexafluorotitanate (K2TiF6) and potassium tetrafluoroborate (KBF4) in molten Al metal contributes to the development of titanium diboride content. The manufactured AA6082-TiB2 AAMCs were evaluated using a scanning electron microscope (SEM) and X-ray diffraction (XRD). The mechanical properties and wear rate (WR) of the AAMCs were investigated. XRD guarantees the creation of TiB2 phases and proves the nonappearance of reaction products in the AMCs. SEM studies depict the even dispersion of TiB2 in the matrix alloy. The mechanical and tribological properties (MTP) of the AAMCs showed improvement by the dispersion of TiB2 particles. The WR decreases steadily with TiB2 and the least WR is seen at nine weight concentrations of TiB2/AA6082 AAMCs. Fabricated composites revealed 47.9% higher flexural strength and 14.2% superior compression strength than the base AA6082 alloy.

“…Another factor for the increase in hardness of the composite samples is because of the bonding strength between the matrix and the reinforcement. The wetting characteristic between the ZnO and AA6061 matrix was perfect and so it does not form the brittle reaction layers (Moses et al , 2016). Hence, the hardness of the fabricated composite samples is high.…”

“…Among the various fabrication processes, stir casting was widely considered to fabricate AMCs because of its flexibility in processing and material handling, and its high economic advantages (Surappa, 2003). AA6061 has excellent mechanical properties such as high strength and ductility, including high corrosion resistance (Pazhouhanfar and Eghbali, 2018; Moses et al , 2016) and it is highly flexible for manufacturers to modify based on the requirements. Fabricating the aluminium alloys reinforced with hard ceramic particles makes changes in morphology by novel grain refinements and it leads to accomplishment of good mechanical properties (Sudarshan and Surappa, 2008).…”

Purpose The most promising replacements for the industrial applications are particle reinforced metal matrix composites because of their good and combined mechanical properties. Currently, the need of matrix materials for industrial applications is widely satisfied by aluminium alloys. The purpose of this paper is to evaluate the tribological behaviour of the zinc oxide (ZnO) particles reinforced AA6061 composites prepared by stir casting route. Design/methodology/approach In this study, AA6061 aluminium alloy matrix reinforced with varying weight percentages (3%, 4.5% and 6%) of ZnO particles, including monolithic AA6061 alloy samples, is cast by the most economical fabrication method, called stir casting. The prepared sample was subjected to X-ray photoelectron spectroscopy (XPS) analysis, experimental density measurement by Archimedian principle and theoretical density by rule of mixture and hardness test to investigate mechanical property. The dry sliding wear behaviour of the composites was investigated using pin-on-disc tribometer with various applied loads of 15 and 20 N, with constant sliding velocity and distance. The wear rate, coefficient of friction (COF) and worn surfaces of the composite specimens and their effects were also investigated in this work. Findings XPS results confirm the homogeneous distribution of ZnO microparticles in the Al matrix. The Vickers hardness result reveals that higher ZnO reinforced (6%) sample have 34.4% higher values of HV than the monolithic aluminium sample. The sliding wear tests similarly show that increasing the weight percentage of ZnO particles leads to a reduced wear rate and COF of 30.01% and 26.32% lower than unreinforced alloy for 15 N and 36.35% and 25% for 20 N applied load. From the worn surface morphological studies, it was evidently noticed that ZnO particles dispersed throughout the matrix and it had strong bonding between the reinforcement and the matrix, which significantly reduced the plastic deformation of the surfaces. Originality/value The uniqueness of this work is to use the reinforcement of ZnO particles with AA6061 matrix and preparing by stir casting route and to study and analyse the physical, hardness and tribological behaviour of the composite materials.
