Experimental study on the current-carrying test of metallized electrode

In this paper, the current-carrying capacity of metalized electrode is studied. The sheet resistance of tested metalized aluminum electrode is 15Ω/□. High-speed camera is applied to record the state of the metalized aluminum electrode under pulsed current. The results show that the metalized aluminum electrode will fracture perpendicular to the direction of current. According to simulation analyses, joule heating and the electrodynamic force induced by magnetic pressure are the main causes for the fracture of metallized electrode.
