Description
Summary:The synthesis of a co-precipitated mixture of tantalum and brass nanoparticles (Ta and Cu/Zn) using a micro-wire-electro-discharge-grinding (µ-WEDG) with a combination of multiple process parameters is explained in this article. Tantalum and brass nanoparticles are produced in a dielectric medium Diel-7500 EDM oil. µ-WEDG represents a cutting-edge mechanical micro-machining technique extensively employed for machining micro rods. This method uses a grinding process that expels debris via melting and evaporation. This process disperses a fraction of nanometre-sized debris within the dielectric medium. Traditionally, this debris consisting of nanoparticles has been classified as unwanted substances and subsequently eliminated from the system. However, it now requires a thorough reassessment for possible usage. Hence, the characterization of tantalum and brass nanoparticles is conducted through Field emission Scanning Electron Microscopy (FE-SEM), energy-dispersive spectroscopy (EDS), and X-ray diffraction (XRD) analyses. The process parameters are capacitance, voltage and spindle speed. The investigation reveals that the mean nanoparticle size of produced tantalum nanoparticles range from 25 to 200 nm, while brass nanoparticles range from 300 to 950 nm. Furthermore, a notable correlation is observed between decreasing capacitance and the corresponding reduction in the shape and size of nanoparticles.
