【Abstract】 At present, Ag-W contact material is used widely. It has well thermal conductivity, electrical conductivity, fusion welding resistance and oxidation resistance.In this paper, the methods and theory of infiltration and mechanical alloying to produce Ag-W contact are recounted in detail. The fusion welding, arc erosion mechanics and corrosion mechanics of Ag-W contact are also discussed.更多还原
