摘　　要：采用内氧化法工艺制备了不含添加剂及分别含添加剂CuO或TeO2的3种AgSnO2In2O3触头材料。应用模拟继电器试验设备检测了这3种材料在AC230 V、25 A阻性负载条件下的电寿命、熔焊力、电弧能量、燃弧时间、质量侵蚀率等相关电性能参数,并对检测结果及试验后铆钉触头样品进行了分析。研究发现:与不含添加剂的AgSnO2In2O3材料相比,添加剂CuO对材料的电寿命影响不大,而添加剂TeO2明显提高了材料的电寿命;含添加剂的两种材料的熔焊力和电弧能量均有了不同程度的降低,但它们的质量侵蚀率却明显增加。Three types of AgSnO2In2O3 contact materials were prepared through internal oxidation method,one without additive,the other two with additives CuO and TeO2 respectively.The parameters related to the electrical properties of these three materials,such as electric durability,welding force,arc energy,arc duration and mass erosion rate,were tested by the relay-simulated test equipment under the resistance load of 230 VAC and 25 A.We analyzed the test results and the rivet contact samples after test,and found that compared with AgSnO2In2O3 without additives,the additive CuO has little effect on electrical durability,while the additive TeO2 can significantly improve the electrical life.In addition,the welding force and arc energy of the two materials with additives were reduced to a certain degree,while the mass erosion rate increased obviously.
