摘　　要：研究了加入元素钴对铜-锌-铝合金组织的影响,利用腐蚀试验研究了元素钴的加入对铜-锌-铝耐脱锌腐蚀性能的影响。研究结果表明,加入钴可以明显地细化铜-锌-铝合金的组织,使粗大的α、β相变成短小的细板条状组织。加入钴可以明显改善铜-锌-铝合金耐脱锌腐蚀性能,确定了铜-锌-铝合金的最佳钴含量。The effects of Co on the microstructure of Cu-Zn-Al alloy and on the dezincification corrosion resistance of alloys by corrosion test were studied.The results confirmed that Co could refine microstructure of alloys and change α and β phases from coarse plate-like to fine short plate-like.The dezincification corrosion resistance was obviously improved with addition of Co.Furthermore,the optimum amount of Co in Cu-Zn-Al alloy was also found.
