In the current study, an optimization process of powder-mixed electrical discharge machining (PMEDM) when cylindrically shaped parts made hardened 90CrSi steel is reported. this SiC powder was mixed into Diel MS 7000 dielectric solution. Additionally, graphite chosen as electrode material. The multi-objective functions were minimizing surface roughness (SR) and wear rate (EWR) maximizing materi...
In this research, Response Surface Methodology (RSM) is used to investigate the effect of four controllable input variables namely: discharge current, pulse duration, pulse off time and applied voltage Surface Roughness (SR) of on Electrical Discharge Machined surface. To study the proposed second-order polynomial model for SR, a Central Composite Design (CCD) is used to estimation the model co...
BACKGROUND Cardiomyocytes cytoarchitecture changes caused by transthoracic countershocks have been focused recently. We aimed to evaluate the effects of electrical discharge application in the mitochondria structure in atrial myocardium of rats. METHODS An electrical cardioverter was adapted to small rodent animals for our research. Electrical discharges were applied to the precordial region ...
