| 摘 要： | 以Bi2O3为添加剂，采用粉末冶金法制备不同掺杂量的AgSnO2触头材料试样。测量Ag对氧化物基片的润湿角，测试了试样的密度、电导率、接触电阻、燃弧能量等参数，分析了 Bi2O3对AgSnO2触头材料润湿性的影响。结果表明，添加适量的Bi2O3对AgSnO2触头材料的物理和电接触性能有明显的改善，Bi2O3含量为1.5%时AgSnO2触头材料的整体性能达到最佳。润湿角随着Bi2O3含量增大呈现出波动增大的规律，与AgSnO2触头材料接触电阻、燃弧能量的变化规律基本吻合。

| Abstract: | AgSnO2contact materials were doped with different amounts of Bi2O3 by powder metallurgy and then submitted for performance tests. The wetting angle of Ag to the oxide substrate was measured, followed by testing the density, conductivity, contact resistance, arc energy and other parameters. The influence of Bi2O3 on the wettability of AgSnO2 contact material was analyzed. The results show that Bi2O3 dopingsignificantly improvesthe physical properties and electrical contact performance of AgSnO2 contact materials. When the content of Bi2O3 is 1.5%, the overall performance of AgSnO2 contact materials reaches a climax. With the content increasing, the wetting angle presents volatility, and the variation of the contact resistance and the arc energy well match with that of the wetting angle. |
