    • The present invention relates to a method for manufacturing the nanostructured powder by a wire explosion in liquid and a device for manufacturing the same. To be more specific, the object of the invention is to provide a method for manufacturing the nanostructured powder by a wire explosion in liquid and a device for manufacturing the same, in which, a metal wire (18) is vaporized in liquid (14) by generating an electrical explosion using the same principle al in gas, with the characteristic of pulsed power, even though the liquid (14) with a low conductivity is used, and the nanostructured powder of a metal wire (18) is produced in the space made by the volume expansion of vaporized vapour, all of which was performed with an understanding that electrical explosion is not so different in principle weather in gas or in liquid. By achieving this object, the present invention can provide an advantage of natural disperse of the nanostructured powder into a liquid, hence either the agglomeration between powder particles or the surface oxidation of the nanostructured powder is not generated, as the powder is not in contact with oxygen in liquid. Moreover, the classification according to size becomes possible with the reduction of the number of processes, hence providing an advantage of an effective application of the nanostructured powder an the economic ripple effect thereto.
    • 本发明涉及通过液体中的线爆炸制造纳米结构粉末的方法及其制造方法。 更具体地,本发明的目的是提供一种通过液体中的电线爆炸制造纳米结构粉末的方法及其制造方法,其中金属线(18)在液体(14)中蒸发, 通过使用具有脉冲功率特性的气体中相同原理的电气即使使用低导电性的液体(14),并且在空间中产生金属线(18)的纳米结构粉末 通过蒸发蒸气的体积膨胀制成,所有这些都是在气体或液体中的原理天气下电爆炸没有太大差异的情况下进行的。 通过实现该目的,本发明可以提供将纳米结构粉末自然分散在液体中的优点,因此不会产生粉末颗粒之间的附聚或纳米结构粉末的表面氧化,因为粉末不与 液体中的氧气。 此外,随着工艺数量的减少,根据尺寸的分类变得可能,因此提供了对纳米结构粉末的有效应用的经济涟漪效应的优点。
