| 摘 要： | 采用光学显微镜，扫描电镜及能谱仪对冰箱用紫铜管渗漏失效进行了分析。结果表明，紫铜管渗漏系腐蚀引发裂纹所致，而涂在铜管表面的油胶中的氯离子是引起紫铜管应力腐蚀开裂的主要因素。

| Abstract: | The cracked pure copper tube was analyzed by the metallography, SEM and EDS. Cl element was detected in the corrosive products. Cl ion was also found in oil glue by chemical analysis method. It was concluded that the Cl ion in the oil glue resulted in stress corrosion cracking of the pure copper tube. |
