| 摘 要： | 采用化学沉积和粉末冶金方法，合成了一种新型石墨烯增强银基电触头材料(Ag-G)，并对其微观结构、加工性能及物理性能进行分析。结果表明，Ag-G材料组织致密、均匀，退火态抗拉强度与断后伸长率分别达到128 MPa和12.1%。DC 25V/15A阻性负载条件下，与传统石墨增强银基电触头材料(Ag-C)比较，Ag-G材料质量损耗、电弧参数及接触电阻均较Ag-C材料偏低，且电寿命为Ag-C材料的2.5倍左右。因其具有优异的加工性能与电接触性能，Ag-G材料有望成为一种替代传统Ag-C的新型电触头材料。

| Abstract: | A new type of graphene reinforced silver-based electrical contact material (Ag-G) was produced by chemical coating and powder metallurgy method, and its microstructure, processing property and physical performance were investigated. The experimental results reveal that Ag-G material has high relative density and uniform structure, and its tensile strength and elongation reach 128 MPa and 12.1%, respectively. Under the electrical contact condition of DC25 V/15 A and resistance load, compared with convenient graphite reinforced silver-based electrical contact material (Ag-C), the weight loss, arc parameters and contact resistance of Ag-G material are lower than that of Ag-C material, and the service life of the new material is 2.5 times as long as that of the Ag-C material. Due to the superior processing property and electrical contact performance, Ag-G may be substitute for Ag-C as a new electrical contact material. |
