Mechanical and Wear behaviour of Al6061 reinforced with Graphite and TiC Hybrid MMC's.

Aluminium (Al6061) with Graphite (Gr) and Titanium Carbide (TiC) particles of different configurations have been prepared using stir casting method. The development of aluminium with Gr and TiC composites has been confirmed with Energy Dispersive Spectrometer (EDS) tests. Scanning Electron Microscope (SEM) study has been performed to identify the configuration of the composite material. In the current work, an attempt is made to study the mechanical and tribological behaviour of Al6061 reinforced with 5wt% Gr for different fraction of TiC hybrid composites. The addition of Gr was maintained constant and equal to 5 wt.% throughout the experiment. TiC was varied from 0% to 8 wt. % in a step of 2%. The effect of addition of Gr and TiC on microstructure, micro hardness, tensile strength, wear resistance were investigated. The results showed that aluminium reinforced with Gr and TiC exhibited better mechanical and tribological properties of composites. [ABSTRACT FROM AUTHOR]
