Effect of additives on the electrical properties of W/WC contacts
W/WC계 접점의 전기적 특성에 미치는 첨가물의 영향
Abstract
W/WC-Cu/Ag contacts of 60wt%-40wt% base and contacts with additives(Ni, Co, C) of 1wt% below were prepared by a press-sinter-infiltrate process to compare with their physical properties and arc erosion characteristics. In physical properties, electrical conductivity of contacts with additive is lower than that of base contacts but hardness is higher. The results of arc test show that the erosion rate of contact with -0.1wt% Ni is decreased.
