Abstract
Erosion mechanism of multi-phase AC arc was investigated for the innovative in-flight glass melting technology. The combination of the high-speed video camera and the band-pass filters was used to measure the temperature of the tungsten electrode during the arc generation. Increase of the number of the phases leads to larger molten surface area of the electrode. The dynamic behavior of tungsten vapor in the arc was investigated by using the same system with the high-speed video camera. The strong emission from tungsten was observed. Results indicated that the tungsten mainly evaporated at anodic period.
