本文叙述了冷等静压-烧结-液体浸铜工艺制取高密度高性能钨-铜触头的工艺过程、工艺参数控制及使用设备。按照对电触头的性能要求测定了所制材料的主要物理机械性能和进行了电弧烧蚀试验。结果表明,用本工艺制取的钨-铜触头具有接近理论密度的高密度、优异的物理机械性能和抗电蚀性。 This article describes the cold isostatic pressing - sintering - liquid immersion copper process to obtain high-density high-performance tungsten-copper contacts of the process, process parameters control and use of equipment. In accordance with the performance requirements of the electrical contacts measured the main physical and mechanical properties of the material and the arc ablation test. The results show that the tungsten-copper contact prepared by this process has high density close to the theoretical density, excellent physical and mechanical properties and resistance to electric erosion.
