초록

As electrode materials like as Cu-Pb, Cu-Bi, WC-Ag, W-Ag for vacuum circuit breaker have high chopping current or bad insulation-recovery characteristics, it can affect induction machinery like as transformer and motor. To produce low surge electrode material, it have been suggested Co-Ag-Te electrode which were infiltrated with Ag-Te intermetallic compound into sintered Co matrix in vacuum. In this paper, we would like to represent that production method and microstructure of Co-Ag-Te electrode material in each condition. The microstructure and characteristics of Ag-Te intermetallic compound and Co-(Ag-Te) electrode were investigated by using optical microscope, SEM, XRD, EPMA.
