Review: Analisation of Mechanical Characterization of Aluminum Alloy 7075 Grade Reinforced with Aluminum Oxide

The mechanical properties of Aluminum Hybrid Matrix Composites (AHMCs) reinforced with Aluminum oxide (AL2O3) particles are investigated in this composition. The matrix material is an aluminum 7075 alloy with Al2O3 particles ranging from 3 to 9 wt percent in increments of 3 wt percent and a set quantity of 3 wt percent alumina. The stir casting technique was used to create the hybrid composites. On the prepared composites, the hardness and tensile characteristics were investigated. The amount of reinforcements increases the tensile strength and hardness of the hybrid composites, according to the findings. Properties and corrosion resistance have been achieved Under optimum conditions, a maximum Young's modulus of over 80 GPa, a maximum hardness of 1.39 GPa, and maximum wear resistance have been achieved. Due to the resistance of Al2O3 particles to corrosion in terms of electrochemical behavior, optimal composites have the lowest thermodynamic corrosion propensity and show higher pitting corrosion resistance. In addition, if the amount of Al2O3 is large, the formation of a continuous protective layer on the surface will be delayed and the corrosion resistance will decrease. The mechanical and wear properties of Al7075 - Al2O3 (3% and 6%) and Al7075 - Al2O3 (6% - 3%) composites are prepared and compared. The composites were made using the stir casting method, with the amount of reinforcement varying from 6 to 12 percent in 3wt% stages. Tests were performed on the Al7075 - Al2O3 composites, and hardness, density, and mechanical and parameters were evaluated according to industry standards.
