Abstract
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-Se electrode which were infiltrated with Ag-Se intermetallic compound into sintered Co matrix. In this study, we would like to represent that production method and microstructure of Co-Ag-Se electrode material. The microstructure and characteristics of Ag-Se intermetallic compound and Co-(Ag-Se) electrode were investigated by using SEM, XRD, EPMA.
