Wear Testing of Stir Casted Al -Al2O3 MMC

Engineering science has done tremendous progress in use of composite material. This paper had shown work of Wear testing, Hardness testing and Tensile testing on Al /Al2O metal matrix composite (MMC). This work has been carried to show strength extension of MMC in contrast to original metal. The MMC of Al /Al2O is fabricated via Stir casting way. Particulate reinforcement has been chosen for this work in contrast to fabric reinforcement because of its isotropic nature and also having advantage that most existing processing techniques can be used for fabrication and finishing of the composites for this type of MMC like hot rolling, hot forging, hot extrusion and machining etc. Experimental work had been carried out on MMC having alloy Al6063 and 10% Al2O3 . Further in experimental work uniform reinforcement distribution is used for effective utilization of the load carrying capacity. Final results shown for Hardness testing taken by Vickers hardness measuring machine also for tensile testing results taken by UTE-100 and paper ended with wear testing results also shown Graph between Coefficient of friction & Frictional Force Versus time under different Load and speed for the purpose of wear testing. All results are taken under Government registered laboratory.
