摘　　要：研究了AgW和AgSnO2电触头材料的力学物理性能以及动态电气性能,分析了材料组织与性能之间的相互关系。在模拟汽车电流、电压等条件下进行了30 000次的通断试验,对电触头材料的转移、粘附与熔焊、触头表面的形貌等进行了分析。Electrical contact materials AgW and AgSnO2 were studied in this paper. By researching the mechanical properties and dynamic properties of the two kinds of materials, the relation between the microstructure and the properties were analyzed. 30 000 on-off tests were accomplished in a simulated car current and voltage conditions, and the material transfer, welding and surface were analyzed.
