摘　　要：介绍了银-金刚石、Ag-TiB_2、Ag-Mg-Ni以及银基氧化物等四种新型银基触头材料,分别对这四种新型银基触头材料的研究状况进行了探讨。分析了各触头材料的工艺、显微组织以及性能特点,并阐明了添加剂对这些触头材料组织和性能的影响。最后,对新型银基触头材料的未来发展趋势及应用进行了展望。Four kinds of novel silver-based contact materials including silver-diamond, Ag-TiB2, Ag-Mg-Ni and silver-oxide contact materials were introduced. The research status of the four kinds of silver-based contact materials was discussed in detail, and the process, microstructure and properties characteristic of these contact materials were analyzed. Moreover, the effects of additives on the microstructure and properties of the contact material were analyzed. Finally, the development trend and application of these new type silver-based contact materials was put forward.
