Analysis and Optimization of Abrasive water Jet Machiningprocesses on the hybrid nano particle reinforced Aluminum alloy matrix composite material

Abstract

Abstract The Nano hybrid particles reinforced aluminium based MMC has been prepared and characterized. The materials chosen for the fabrication of the composites include Aluminium Al6061 alloy(70%) as the base or matrix material in the composite reinforced with hybrid Nano materials as the particulate reinforcements (Cu-9%, Gr-9% and Al2O3-12%) were prepared by following the stir casting route. The developed material has been characterized and subjected to AWJM process. The input parameters were carefully chosen. The Experimental design was formulated for the orthogonal array of L30. Observations were made and the results were taken to the Design Expert software so as to do the optimization process. Reinforcing a hybrid mixture comprising of an alloy, a metal, a ceramic and allotropy of carbon in the matrix and analysing their properties are in itself unique and such works are scanty. The material thus fabricated showed few novel characteristics. The conduciveness of processing the material, aimed at providing the good quality surface and the ease of reducing the bulk material were investigated. Unique tool for optimization proposed by RSM “the Central composite Design” was put in to use in this work. Bearings, Bushes etc. known for their structural supports could be manufactured using this material exhibiting good machinability aspects.
