Effect of hybrid ceramic addition on Al7075 for prompt utilization

In recent engineering applications, lightweight aluminium composites are becoming more popular as an alternative for ferrous metals. The high cost of component manufacture has kept particulate metal matrix composites from being widely used in engineering applications. The goal of this research is to characterize stir cast Al-7075/B4C/Si3N4 reinforced hybrid composites. Hard ceramic reinforcements increase the microstructure, mechanical, and wear qualities of the material. B4C and ZrB2 particles were incorporated into the Al matrix at different weight percents, such as 2, 4, 6, and 8. The microstructure, and properties of mechanical as well as wear of ZrB2 and B4C particle composition were examined. In addition, SEM and XRD were used to investigate the castings' morphology. As a result, hardness and strength rise as the amount of B4C-ZrB2 in the composite increases. The Al7075 + 8% B4C + 1% ZrB2 composite outperform all the considered composition. Furthermore, with increasing sliding distances, the specific wear rate increases and the coefficient of friction decreases. Because of its outstanding mechanical and wear properties, the hybrid Al7075-B4C-ZrB2 material is the excellent choice of upper wing requirements.
