Abstract: The present research work has been given the importance on proper distribution of silicon carbide nano particles with different volume fractions of 1%, 1.5% and 2% in the aluminium metal matrix. The paper also deals with the wear analysis of the developed Al-SiCp nano composite by using dry sliding wear test with pin on disc machine. XRD analysis of the Al-SiCp nano composite work material has been performed to determine the purity and grain size of the sample. The present work also focuses on metal matrix nano composites during electric discharge machining (EDM) process using brass, aluminium and copper as tool electrodes. Electrode wear ratio (EWR) of the tool as well as material removal rate (MRR) of the workpiece has been determined and it was found that copper is the best and preferable electrode followed by aluminium and brass electrodes due to its higher MRR and lower EWR.

Keywords: wear; material removal rate; MRR; electrode wear ratio; EWR; electro discharge machining; X-ray diffraction; XRD; nano composite; purity; grain size.
