摘　　要：文章通过盐雾腐蚀实验、显微组织分析、微区成分分析等对铜银合金接触线、铜锡合金接触线和铜镁合金接触线的耐蚀性能进行了研究。结果表明,铜银合金、铜锡合金和铜镁合金接触线的年化腐蚀速率均在同一水平,其中铜银合金和铜锡合金的耐蚀性能评级均优于铜镁合金。In this paper,the corrosion resistance of copper-silver alloy contact wire,copper-tin alloy contact wire and copper-magnesium alloy contact wire are studied by salt spray corrosion tests,microstructure analysis and micro-area composition analysis.The results show that the annual corrosion rates of copper-silver alloy,copper-tin alloy and copper-magnesium alloy contact lines are all at the same level,and the grade of corrosion resistance of copper-silver alloy and copper-tin alloy is better than that of copper-magnesium alloy.
