摘　　要：采用反应合成法结合塑性变形工艺制备了不同SnO_(2)含量的AgCuOIn_(2)O_(3)SnO_(2)电触头材料,在JF04C触点材料测试机上对不同SnO_(2)含量的电触头材料进行电接触实验,研究了该材料的接触电阻、抗熔焊性和材料转移特性,并通过扫描电镜对试样阴/阳表面电侵蚀下的微观形貌进行了分析。结果表明AgCuOIn_(2)O_(3)SnO_(2)触头材料接触电阻小,当测试电压不超过12 V时,接触电阻随测试次数的增加呈现缓慢下降最后趋于稳定的趋势,当电压增大到18 V时,各试样的接触电阻均增大,且增幅程度不一。对于SnO_(2)含量不变的试样,熔焊力随着测试次数的增加呈现先增大后减小的趋势,材料的燃弧能量随电压的增大而增大,随着测试次数的增加呈锯齿形波动。电接触过程材料主要为阴极转移,材料的损耗量随SnO_(2)量的增多先增大后减小,阴/阳极触头表面呈凸凹状,且表面存在熔融金属液凝固状花样,材料转移主要以熔桥方式进行,当SnO_(2)含量在0.5wt%~1.0wt%时,电接触性能最为优异。The AgCuOIn_(2)O_(3)SnO_(2) electrical contact materials with different SnO_(2) content were prepared by the reaction synthesis method combined with the plastic deformation process.Electrical contact experiments were carried out on electrical contact materials with different SnO_(2) content on the JF04C contact material testing machine,and the contact resistance,welding resistance,and material transfer characteristics of the material were studied.The microscopic morphology under erosion was analyzed.The results show that the contact resistance of AgCuOIn_(2)O_(3)SnO_(2)contact material is small.When the test voltage does not exceed 12 V,the contact resistance decreases slowly with the increase of the number of tests and finally tends to stabilize.When the voltage increases to 18 V,the contact resistance of each sample is equal increase,and the degree of increase varies.For samples with constant SnO_(2) content,the welding force first increases and then decreases with the increase of the number of tests.The arcing energy of the material increases with the increase of the voltage,as the number of tests increases,it fluctuates in a zigzag shape.The material in the electrical contact process is mainly cathode transfer,and the loss of the material first increases and then decreases with the increase in the amount of SnO_(2).The surface of the cathode/anode contacts is convex and concave,and there are molten metal solidification patterns on the surface.The material transfer is mainly carried out by melting bridge,and the electrical contact performance is best when the SnO_(2) content is 0.5wt%-1.0wt%.
