| 摘 要： | 为节约Ｃｒ资源，提高ＣｕＣｒ触头材料的耐电击穿性能并满足其大规模生产的需要，根据Ｗ、Ｃｏ的选择相强化作用，以钝Ｃｕ、Ｃｒ块为原料，采用Ａｒ气保护熔炼法制备ＣｕＣｒ２５Ｗ１Ｃｏｌ头合金，并对其性能进行研究。实验结果表明，该合金晶粒尺寸细小，含气量低，耐电压强度已达到常规头材料的水平。

| Abstract: | CuCr25W1Co1 electrical contact alloys were prepared by a vacuum smelting method and their properties were measured. The results show that selective strengthening by W and Co improves the breakdown fields of CuCr alloys, and that vacuum smelting is an effective method to produce CuCr contact material, it saves Cu and Cr, improves properties, and is suitable for large scale production. |

| Keywords: | CuCr contact material selective strengthening vacuum smelting breakdown field |
