Abstract

The aim of this research article is to fabricate and study the behavior of aluminum nano composites (ANCs). The aluminum nano composites were commonly used for higher performance applications such as military, aerospace, and automotive because of their enhanced properties such as mechanical, physical, and wear. The zinc oxide (ZnO) nano-sized particles were synthesized by using a simple combustion method. The synthesized nanoparticles were characterized through X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and EDX analysis. The fabrication of nano composite, ZnO NPs were used as reinforcement and Al-Si7.0-0.5Mg alloy as the base alloy. The synthesized ZnO NPs were added with base alloy with various percentages ranges from 1.0, 2.0, 3.0, 4.0, and 5.0 Wt.% through stir casting method. Wear test was carried out at varying weight of reinforcements verses varying load and constant speed. The obtained reveal that the microhardness is improved with addition of 5wt.% of ZnO NPs. The rate of wear enhanced with increasing the percentage of reinforcements at 5 wt.% of ZnO NPs
