摘要

In the present scenario, there is a great demand for lightweight and strong materials for a variety of applications, including batteries, supercapacitors, energy devices, fuel cells, and solar energy conversion. Utilize a composite material to achieve all the properties in the current environmentally friendly surroundings in order to meet this need. In this work, the inclusion of Aluminium-Magnesium-Silicon (Al-Mg-Si) alloy matrix material is reinforced with graphene oxide (GO) and manganese dioxide (MnO2) nanoparticles made from agricultural wastes such as coconut shell and sugarcane bagasse. The Al-Mg-Si/GO/MnO2 hybrid metal matrix nanocomposites are made utilizing ultrasonic aided stir casting. The effects on corrosion, microhardness, micro tensile, impact, density, and wear, among other chemical, mechanical, physical, and tribological characteristics, was examined and contrasted with the base alloy Al-Mg-Si. Optical microscopy and field emission scanning electron microscopy have been utilized to study the microstructure, rupture, and micro tensile and wear samples. Among all compositions, the hybrid composite of 1 wt.% GO and 1 wt.% MnO2 exhibited the highest effectiveness. The rate of corrosion was greatly lowered, with the hybrid composite showing a maximum decrease of 54.2% when compared to the base alloy. Significant changes have been noted, with the hybrid composite having microhardness increased by 28.3%, tensile strength improved by 28.6%, wear resistance increased by 41.8% when compared with the base alloy; however, impact strength was decreased by 25.8%. The presence and even dispersion of nanoparticles of GO and MnO2 were confirmed by EDS and EDAX analysis, whereas the microstructure showed that the nanoparticles were dispersed evenly without much agglomeration. The research results showed the great potential of affordable reinforcing materials that include agricultural wastes, such as sugarcane bagasse and coconut shell, as well as GO and MnO2, for implementation in battery and supercapacitor applications.
