동시 전기 폭발법에 의한 나노 합금 분말 제조에 관한 연구Part I - 동시 전기 폭발을 위한 이론적 배경

Abstract

Pulsed wire evaporation (PWE) method is known as the promising production-technique for nano powders. In this study, we developed and modified the previous single wire explosion equipment to the simultaneous two-wire explosion one for the fabrication of alloy or mixture of nano metallic powder. First of all, both the theoretical and empirical background of pulsed wire explosion of single wire were summarized, and compared with our experimental results for Cu and Al single wire explosion. After then, the simultaneous wire evaporation equipment was designed, constructed, and tested. The current and voltage behavior were well matched between the calculated ones from the circuit equations, and the experimental results from simultaneous explosion of Cu and Al wire.
