Fabrication and Studieson Mechanical properties of Multi walled Carbon Nanotube Reinforced Aluminium 6061 hybrid composites.

Abstract

Hybrid nanocomposites are based on aluminium alloy reinforced with different hybrid ratios of Graphite (1%, 2%, 3% &4 weight %) and Multi walled carbon nanotube (MWCNT) (fixed 2 weight %) nanoparticles were successfully mixed by using planetary ball mill and compacted by using novel technique powder metallurgy. The core of work, it is intended to develop and study the properties of Aluminium 6061(Al6061) /MWCNT/Graphite reinforced hybrid aluminium metal matrix composites. The fabricated specimens were characterized using Scanning Electron Microscope (SEM) with X-ray diffraction(XRD), and hardness test. it was observed that the MWCNT and graphite was fairly dispersed in the Al6061 metal matrix composites. The hardness of this composites is increased for 1% graphite and MWCNTs as compared with the aluminium 6061 alloy and hardness decreases with increases graphite percentages.
