چکیده | ||
The objective of this study is to examine how the input parameters of wet-EDM, near-dry (ND-EDM), and NDPM-EDM affect the output performances of the newly fabricated metal matrix composites (MMCs) of aluminum Al-7075/MSGNP nanocomposites produced by the stir-casting. Air, Ar, mix (Ar+N2), and Ferron gases were included in the current study, which used vegetable oil as a dielectric medium. Additionally, Kaolinite Nano powders were employed as an additive in ND-EDM studies. The data obtained indicate that the greatest MRR attained in the ND-EDM process was 29.425 mm3/min when vegetable oil and Freon gas were used. In the NDPM-EDM, the highest achieved MRR obtained using the Freon gas reached 15.468 (used 800 µsec, 5% Al2SiO2(OH)4). The obtained result is higher than the highest value obtained when using vegetable oil alone by 209.37%. The lowest achieved EWR obtained using the Freon gas reached 0.003 with the vegetable oil + 5% and 10% Al2SiO2(OH)4). The lowest achieved SR for all the implemented experiments, was obtained with used the Freon additive gas to dielectric, reached 4.797 µm (used 5% Al2SiO2(OH)4). The SR value obtained is 19.88% lower than the minimum value achieved when using only vegetable oil. The SEM study showed that the average thickness of the recast white layer was significantly reduced when using the ND-EDM approaches compared to the standard wet-EDM method. The decrease percentages for introducing air, Ar, mix (Ar-N2), and Freon gases into the vegetable oil dielectrics for ND-EDM were 108.17%, 165.51%, 630.26%, and (∞). | ||
