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,以纯Cu、Cr块为原料,采用Ar气保护熔炼法制备CuCr25W1Col触头合金,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触头材料的水平。
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.
