Abstract
In recent years, nano-doped metal matrix composites have started to take place among the developed composites. In this study, powder metal undoped ZA27 alloy and 0.5% wt% multi-walled carbon nanotube (MWCNT) doped nano-composite machinability in EDM (electrical discharge machining) were researched. Microstructures of ZA27 nano-doped composites were examined under a scanning electron microscope (SEM), and their hardness measurements were made. Obtained test results were compared with that of ZA27 samples without nanodoped. In the SEM analysis, the production method applied was generally successful, and the porous regions encountered in some parts of the composite structure were due to the difficulty in homogeneously dispersing the MWCNT reinforcement material. The metal’s material removal rate (MRR) increased with the addition of MWCNT powders that raised conductivity and decreased tool wear rate (TWR) compared to the pure ZA27 material.
