摘　　要：采用扫描金相—微区成分分析,拉伸力学性能测试和x射线衍射生物相分析等手段对加入微量的砷、硼和稀土Ce黄铜冷凝管的腐蚀特性进行了观察和分析。结果表明:不仅单独加入微量的砷、硼和稀土Ce能抑制HSn70-1黄铜冷凝管的脱锌腐蚀,砷、硼和稀土Ce的联合加入能更有效地协同抑制HSn70-1黄铜冷凝管的脱锌腐蚀。The corrosion characteristics of the yellow copper condenser tubes containing trace elements, such as As, B, and rare earth （RE） Ce, were observed and analyzed by using metallography-energy spectrum, tensile test and XRD analysis techniques, etc. The results indicated that the dezinc corrosion of the HSn70-1 yellow copper condenser tubes was resisted less effectively by adding the trace elements As, B, and rare earth （RE） Ce separately than by adding all three trace elements together.
