AgNilO CONTACTING MATERIALS MADE BY COPRECIPITATION SINTERING AND EXTRUSION

A new technology of coprecipitation,sintering and extrusion with the feature of powder made by substituting mechanical mixing and rolling with coprecipitation and hot-extrusion is mainly discussed.This technology exhibits advantages of two processes,both mechanical mixing,sintering and extrusion and coprecipitation,sintering and rolling,improving quality and utilization of materials and giving AgNi10 P/M electric contactors high strength of matrix,hemogencous distribution of nickel particles,fibrous for mation of power and other superior mechanical and physical properties.
