Modification of Die Sinking-Electrical Discharge Machine (EDM) for Production of Titanium Carbide Nanoparticles

Nanomaterials have been gaining significant interest recently, where they can be fabricated via various methods. This work was carried out to study the production of titanium-based nanoparticles by a die sinking typed electrical discharge machine (EDM). The small sink bath was designed and built for the nanoparticle production in a limited volume to protect the leakage of the obtained nanoparticles through the filter system in EDM. The titanium bar was milled under a dielectric oil. The obtained nanoparticles were separated from the oil, and then the morphology of the titanium nanoparticles was examined through a scanning electron microscope. It was found that the particle size of nanoparticles was less than 100 nm. From the examination of crystal structures via an X-ray diffractometer, it was found that the titanium nanoparticles obtained were titanium carbide which was caused by the reaction of carbon from the oil with the metal.
