中文摘要：

用全浸失重法，研究了碲铜系合金在饱和NH4Cl溶液中的抗腐蚀性能，结合扫描电镜（SEM）、能谱仪（EDS）等测试方法，初步探讨了合金在饱和NH4Cl溶液中的腐蚀行为及腐蚀机制，结果表明：碲铜系合金的抗腐蚀性优于纯铜，其腐蚀速率低于纯铜，原因在于碲、镁的加入，可降低纯铜中的非金属杂质含量，同时碲、镁的加入，可沿铜晶界以化合物的形式析出，有利地阻碍了纯铜的沿晶腐蚀。

英文摘要：

The anti-corrosion properties of Cu-Te series alloys in the NH4Cl solution were studied by the method of immersion testing. Combined with SEM and EDS, the anti-corrosion mechanics and behavior were researched. The results showed that Cu-Te（-Mg） alloys were less corroded than pure copper and the corrosion rate of alloys was lower than that of pure copper. The reason is that addition of Te/Mg can decrease non-metal impurities of commercial copper. At the same time, Te／Mg can precipitate as the second phase along the grain boundary of copper, thus retarding the corrosion rate of copper.
