摘　　要：研究了微量稀土元素钇(Y)添加对Sn-9Zn合金组织及电化学腐蚀特性的影响。结果表明:微量Y元素在Sn-9Zn钎料中的添加能够显著细化合金组织;电化学腐蚀过程中,添加微量Y后Sn-9Zn合金中较为细小的混合组织腐蚀原电池反应较为均匀,耐蚀性提高。The effects of minor Y additions on the microstructure and the electrochemical corrosion behavior of Sn-9Zn alloy were investigated. The results indicate that the microstructure in Sn-Zn-Y solder alloys is refined by the additions of minor Y. The galvanic corrosion reaction of the alloy is uniform due to its uniform mixture structure in electrochemical corrosion process. The corrosion resistance of the alloy is improved by the minor Y addition.
