摘要
介绍了贯穿复合银/铜熔体材料的研发和生产现状。复合银/铜熔体材料可替代目前广泛使用的纯银带用于熔断器行业。贯穿复合材料的坯料通过组合烧结的方式制备,界面添加银铜合金以提高结合强度;烧结后经过多道次轧制和热处理获得所需要的带材尺寸。该新型熔体材料较好地解决了熔断片与基座不易焊接的难题,同时节约贵金属银的用量,具有很好的推广应用前景。
Status of research and production of cross-layered Ag /Cu composite is introduced in this paper. This composite can be used to take place of pure silver strip in fuses. The cross-layered blank was fabricated by combination sintering. Ag-Cu alloy was placed in the interface between pure silver and pure copper so as to increase the bond strength. The sintered blank was then multi-pass rolled and heat treated to obtain the expected gauge. The welding difficulty between the pure silver fuse and the base is overcome effectively by applying this novel Ag/Cu composite. And the consumption, of silver for fuse is decreased significantly. Therefore, the composite shows an extensive application prospect.
