摘要
采用熔渗法制备AgW(65)触头材料,对不同骨架制备工艺获得的AgW(65)触头材料的金相组织和性能进行了比较,分析了骨架制备工艺对材料金相组织和性能的影响。结果表明,采用纯W骨架坯制备的触头材料具有良好的综合性能,其具有金相组织均匀、密度高、电阻率低、硬度高的特点。
AgW(65) contact materials were prepared by infiltration. Microstructures and properties of AgW(65) contact materials by different kinds of skeleton preparation technology were compared.The influence of skeleton preparation technology on microstructures and properties of materials were analyzed. The results show that the contact materials prepared by pure tungsten skeleton have excellent comprehensive properties, with characteristics of homogeneous microstructures, high density, low resistivity and high hardness.
