本文讨论了表面涂层对爆炸丝性能的影响。研究了三种不同厚度和材料的表面涂层，每种涂层都具有99.99%的纯银导电芯。实验上，线经受超过107 A/cm 2的微秒时间尺度上的峰值电流密度。高速增强型电荷耦合器件（iCCD）图像。已经开发了一个理论一维有限差分模型来预测线材行为，并确定由表面涂层的存在引起的行为偏差的机制。
This paper discusses the effect of surface coatings on exploding wire behavior. Three different surface coatings of different thicknesses and materials have been studied, each with a 99.99% pure silver conducting core. Experimentally, the wires are subjected to peak current densities in excess of 107 A/cm2 on a microsecond time scale. High Speed intensified Charge-Coupled Device (iCCD) images. A theoretical one-dimensional finite difference model has been developed to predict wire behavior and determine the mechanism(s) responsible for the deviations in behavior induced by the presence of a surface coating.
