ABSTRACT In this study, investigation has been conducted in the focus of obtaining better surface finish in the electro discharge machining (EDM) of AZ91/5B4Cp magnesium composites using distinctive sort of anode viz. copper, tungsten–copper, brass, aluminum and 20Gr/AA6061 (GRAL-20) composites. The process parameters, pulse on time and current were performed to research the machining qualities through material removal rate (MRR) and tool wear rate (TWR). The machined composites were examined by optical microscopy (OM) and scanning electron microscopy (SEM). The formation of black spots was observed on machining with copper–tungsten and these black spots were not found when GRAL-20 was used as electrode. Machined with GRAL-20 electrode leads to the increase in spark gap, hence adequate flushing occurs; it eliminates re-melted layers on machined surface results in better surface roughness value. The results revealed that GRAL-20 electrodes posses better MRR followed by copper electrode whereas tungsten–copper exhibits better TWR followed by GRAL-20 electrode.

ABSTRACT The present study focuses on the investigation of environmental effects of adding aluminum oxide (Al2O3) nanoparticles as nano-additive in diesel-pyrolyzed biomass oil (PBO) blends. The PBO was extracted from jatropha seeds through the catalytic pyrolysis process at a temperature ranging from 450°C to 550°C. The esterification of PBO has been carried out using a catalyst in the presence of methyl alcohol to improve its physical properties and quality. The Al2O3 nano-additives were dispersed into PBO20 (20% of PBO and 80% of diesel) and PBO40 (40% of PBO and 60% of diesel) blends with a concentration of 50 ppm. The physical properties of test fuel blends were measured and compared with diesel. The engine emission tests were carried out using these blends at a constant speed of 1500 rpm by varying the load. The emission constituents such as CO, HC, and smoke were reduced. However, the emissions like CO2 and NO were increased by the addition of nano-additives compared to diesel.
