摘要
AgNi合金是一种综合性能优良的节银电触头材料。本文概述了AgNi合金电触头材料制备技术的研究现状及进展,重点介绍了机械混合法、化学共沉积法、机械合金化法3种主要制备方法。由于AgNi电触头材料的应用受到大负荷下抗熔焊性差的制约,因此还讨论了改善AgNi电触头材料抗熔焊性的途径,最后对其未来的发展方向进行了展望。
AgNi alloy is a kind of electrical contact materials, which has excellent comprehensive performances. In this work, the preparation technology and research developments of AgNi contact material were summarized, and three main preparation methods were focused on, i.e. mechanical mixing, chemical co-precipitation and mechanical alloying. One obstacle for the use of AgNi alloy is the lack of good melting welding-resistance, so the improvement of melting welding-resistance of AgNi contact material was discussed. At last, the development directions of AgNi contact material in the future were expected.
