A ROLL TYPE BODY WITH MICRO/NANO DUAL STRUCTURE FORMED BY ELECTRIC DISCHARGE MACHINING AND THE APPARATUS FOR CONSTRUCTING MICRO/NANO DUAL STRUCTURE ON THE ELEMENT SURFACE USING THE SAME

摘要

PURPOSE: A roll-type structure with a micro and nano dual structure using electric discharge machining(EDM) and an apparatus for forming the micro and nano dual structure on the surface of a base substrate using the same are provided to prevent the surface defects of the structure and to guarantee excellent sustainability and easy manufacturing work by directly forming a micro and nano dual structure on the surface of the structure with EDM. CONSTITUTION: A roll-type structure(200) has a micro pattern(210) and a nano surface roughness(220) on the surface thereof. The micro pattern is formed by EDM using a wire. The nano surface roughness is formed on the surface of the structure by sparks generating in the EDM process for forming the micro patterns.
