Abstract—

In electromagnetic generators of the terawatt range with current pulse of 1–30 MA, electric explosion of the surface of current-carrying electrodes takes place. One of the options for protecting the electrodes is covering the current-carrying surface with different materials. In this work, we present experimental data and results of numerical simulations of the processes that take place in a thick-walled heterophase electrode during the passage of current with a high linear density. The amplitude value of the linear current density in the simulations was of 2.8 MA/cm. The results of the simulations of the processes that occur in the electrodes during the passage of current with high linear density are in qualitative agreement with experimental data.

摘要-

在具有 1-30 MA 电流脉冲的太瓦范围的电磁发电机中，载流电极表面会发生电爆炸。保护电极的选择之一是用不同的材料覆盖载流表面。在这项工作中，我们展示了厚壁异相电极在高线密度电流通过期间发生的过程的实验数据和数值模拟结果。模拟中线性电流密度的振幅值为 2.8 MA/cm。在高线密度电流通过期间电极中发生的过程的模拟结果与实验数据定性一致。
