  • Arc erosion behavior and mechanism of Ag/Ti3SiC2 cathodes

    Jan 15, 2021The high temperature of the arc first melts the Ag matrix, which leads to the formation of a molten pool. In the sequence of sulfur hexafluoride, nitrogen, and oxygen, the arc energy gradually increases. In sulfur hexafluoride (Fig. 11b), the good wettability between the Ag phase and Ti 3 SiC 2 results in the superior viscosity of the arc erosion region. This hinders the flowing and splashing of the
