Abstract :
In the paper, the results of direct observation of liquid metal behavior under cathode spot plasma of low-current vacuum arc carried out with high time and spatial resolution are presented. Novel data on interdependence of the forming liquid-metal microstructures and cathode spot moving have been obtained.
