Improving the microstructure and mechanical properties of the nanocomposite's material (Al + ZnO).

The aim of this study is to investigate the mechanical characteristics and microstructural characteristics of aluminum matrix with varying concentrations of ZnO (3, 6, 9, 12, 15) wt.%. The Al/ZnO nanocomposite specimens were prepared by powdered metalworking. Due to their high strength, wear resistance, and low weight, aluminum matrix nanocomposites (AMNCs) are crucial alloys for various applications, including automotive, electronics, and aerospace. The specimens used in this study were subjected to a variety of tests, such as X-Ray Diffraction (XRD) analysis and Field Emission Scanning Electron Microscopy (FESEM), to determine the microstructure and phases of the nanocomposites. Additionally, mechanical tests such as compressive, wear, and micro-hardness tests were performed. By using FESEM and XRD analysis, the findings of this study demonstrate that ZnO nanoparticles have been uniformly dispersed in the Al matrix. Although mechanical testing indicate that increasing compressive strength at 15%, the highest microhardness at 15wt.% and also improving wear rate. The aims of this work is evaluation the mechanical properties of nanocomposites materials when they mixing the materials is ZnO and AL matrix. Aluminum matrix composites have shown a wide field of industrial applications. Many advantages offered by aluminum matrix composites involve economic (low energy and low cost), environment (low airbome fallouts) and performance (improving rate of productions). However, the applications of AMCs depend on the characteristics of reinforcement material and the technique of manufacturing. Aluminum matrix composites reinforced by oxides such as Al2O3, carbides such as TiC or B4C, Nitrides such as TiN have been used for thermally applications such as aerospace and rotating bldes of helicopters. Also, used for automotive, cam shafts and arm of automobiles. Aluminum matrix composites used in sporting which involves golf clubs, frames of bicycle and skating shoes. The increment of ceramic concentration in aluminum matrix made it suitable in electrical applications such as microprocessors in electronics [1]. [ABSTRACT FROM AUTHOR]
