Abstract
The present work deals with the outcomes of a novel approach for developing a multi-walled carbon nanotube-reinforced hybrid aluminium metal matrix composite. Microwave hybrid sintering in combination with cold compaction of the powder metallurgy route was followed for the fabrication of composites. Microwave hybrid sintering was carried out using a microwave oven operating at 2.45 GHz frequency and 900 W power. For this purpose, Al5083 was used as the matrix material, and silicon carbide (15 wt.%) and multi-walled carbon nanotubes (0.5 wt.%) the reinforcements. The fabricated composites were then characterized by hardness, microstructure, and porosity. An investigation on the wear resistance of the base alloy and the conventional and microwave sintered composites followed this. The findings of the present study reveal the fact that the addition of carbon nano-tubes in the composite and the use of microwave energy over conventional sintering have a significant effect on the property enhancement of the developed hybrid composite.
