| 中文摘要: |
| 综述了3种新型银基电接触材料的性能特点。以NiO、Bi2O3或CuO改性的Ag/SnO2MeO可以改善传统Ag/SnO2电接触材料的接触电阻稳定性、温升控制及室温加工性；以Ag/Ti3SiC2和Ag/Ti3AlC2为代表的三元层状化合物陶瓷相增强银基材料(Ag/MAX)可以改善AgNi材料大电流条件下的抗熔焊性能，降低直流负载条件下材料转移量；用石墨烯替代传统石墨研制的Ag/GNPs可以解决表面膜增厚、接触电阻增大、耐磨性不足等缺点。提出新型银基电接触材料的主要研发方向。 |
| 英文摘要: |
| The performance characteristics of three types of new silver-based electrical contact materials were reviewed. The stability of contact resistance, temperature control and machinability at room temperature of traditional Ag/SnO2 contact materials were enhanced by the introduction of NiO, Bi2O3 or CuO component. The anti-welding behavior of the Ag/MAX electrical contact materials such as Ag/Ti3SiC2 and Ag/Ti3AlC2 under heavy current was improved, and the materials transfer under DC load was reduced. Ag/GNPs with graphene solves the drawbacks of thickened surface film, increased contact resistance and insufficient wear resistance, compared to Ag/GNPs with graphite. The directions of future development were also presented in this paper. |
