| 中文摘要: |
| 目的 研究在氯化铵存在条件下，铜的大气腐蚀行为。方法 采用扫描电子显微镜（SEM）、能谱（EDS）、傅里叶红外光谱（FT-IR）、X射线衍射（XRD）、滴定法和电化学等方法来确定铜的大气腐蚀过程和腐蚀产物。结果 随着暴露时间的延长，铜的腐蚀质量损失变大，平均腐蚀速率变小。在氯化铵存在条件下，铜表面生成了Cu2O、Cu2(OH)3Cl和Cu2(OH)2CO3，其中Cu2O为主要腐蚀产物，其质量占腐蚀产物总质量的97%以上。结论 氯化铵的存在会对铜造成很强的腐蚀，随着暴露时间的延长，铜的腐蚀变得严重，但是暴露后期腐蚀速率将会减缓。 |

| Objective To study the initial atmospheric corrosion behavior of copper in the presence of ammonium chloride particles. Methods SEM, EDS, FT-IR, XRD, titration method and electrochemical method were used to identify the corrosion process and corrosion products. Results The mass loss of copper increased with exposure time; Cu2O, Cu2(OH)3Cl and Cu2(OH)2CO3 were formed on the copper surface in the presence of ammonium chloride particles, among which Cu2O was the main corrosion product, and its weight accounted for more than 97% of the weight of the total corrosion products. Conclusion The presence of ammonium chloride can cause heavy corrosion to copper and the corrosion of copper becomes more severe with the exposure time. However, the corrosion rate becomes slow in the later period. |
