Machinability investigation and surface modification of nano-TiB 2 and AlN grafted MWCNT hybridized Al 7075 matrix ternary composite through powder-mixed EDM
This paper accentuates powder-mixed electrical discharge machining (EDM) performance of a newly designed nano-TiB2 and AlN grafted multiwall carbon nano-tube (MWCNT) hybridized Al 7075 matrix ternary composite. The hybrid metal matrix composite (MMC) was fabricated through squeeze casting route, preceded by two-stage reinforcement addition, mechanical agitation, and ultrasonic treatment. EDM was carried out using cryogenic treated Cu electrode and Al2O3 particle-mixed dielectric medium. Influence of EDM process variables, that is, peak current (IP), pulse-on time (TON), and powder concentration (PC) on machinability of the hybrid MMC was studied considering material removal rate (MRR), tool wear rate (TWR), and average surface roughness (Ra) as quality indicators. Effects of machining and Al2O3 particle addition on surface morphology of the hybrid MMC were also explored through scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and elemental mapping. Results reveal elevation of MRR, reduction of TWR and improvement of surface finish during powder-mixed EDM in comparison to the non-mixed (conventional) EDM. Maximum traces of Al2O3 particle deposition was identified on the machined surfaces while using the powder concentration of 1.5 g/l within the dielectric.
