The Design of Successful Arcing Rate Measuring Unit for Preparing Nano-Silver Colloid by Electrical Discharge Machine

CODEN: JTEVAB

Abstract

This study used the arc discharge generated by an electrical discharge machine to melt metal silver into nano-sized particles. The manufacturing process was free from chemical agents, while only deionized water was used as the dielectric fluid. The process parameters and discharge pulse width were set to prepare silver nanoparticles suspended in the dielectric fluid, and the process was simple and rapid. However, the process parameters were closely related to success in the discharge. Among them, the discharge pulse width had the most significant effect. Therefore, this study developed a successful arcing rate measuring unit and discussed the effect of different process parameters on the success rate of preparing nano-silver colloid. Silver with a purity of 99.9 % was selected as the main research subject. The results showed that under the same process parameters, the arcing rate is not an exact value but a range value, and the 30 μs-30 μs discharge pulse width is identical as the optimum process parameter. When preparing the nano-silver colloid, the higher the processing efficiency, the shorter the diameter of the particle.
