Effect of the powder concentration and dielectric flow in the surface morphology in electrical discharge machining with powder-mixed dielectric (PMD-EDM) (2008, methodology): “Actually, the low discharge energy and the small electrode-workpiece distance lead to difficulties in gap cleaning, to the capacitive effect enhancement and to the discharge ignition delay [3, 4].”
Surface integrity in metal machining - Part I: Fundamentals of surface characteristics and formation mechanisms (2021, background): “discharge behaviour, and therefore change resulting recast layer properties [235,236].”
Study on the nano-powder-mixed sinking and milling micro-EDM of WC-Co (2011, background): “A surface may not be glossy, although it has lower average surface roughness if the surface has non-uniform crater distribution and variations in crater boundaries which scatter light in multiple directions making the surface dull [4, 14 , 19].”
A review on current research trends in electrical discharge machining (EDM) (2007, methodology): “The characteristics of the powder such as the size, type and concentration influence the dielectric performance [46].”
