Aluminium-based hybrid composites have the advanced applications for their better qualities like high strength-to-low weight ratio and improved hardness than pure aluminium. This research work has carried out to improve the mechanical and wear properties of AA7475 aluminium alloy due to their need in the structural areas and automotive industry. Hence, the reinforcement of 15 wt.% zirconium silicate (ZrSiO4) with AA7075/SiC composites in different SiC percentages has been carrying out using stir casting. The advanced microscopy technique is used to study the microstructure of virgin matrix and their hybrid composites. Archimedes’ principle is used to evaluate the density of hybrid composites and its effects on void content in hybrid composites are studied. The effect of reinforced zirconium silicate (ZrSiO4) in the AA7475 was analysed by the observed hardness, tensile and compressive behaviour in composites. Finally, the wear rate and worn-out surface is studied. The overall analysis found that the microstructure of composites has been identified that SiC and ZrSiO4reinforcement particles have spread evenly in matrix alloy. The Al4C3phase has been observed in the hybrid composite surfaces. The 23.8% hardness, 46% tensile value, 52% yield value, 11% compressive value strength and 46.42% wear rate have been enhanced by adding reinforcements with matrix. |
