| 摘 要： | 采用金相检验、X射线衍射、扫描电影能谱及热重分析法研究了涂有NaCl盐膜的铝青铜在700～900℃的氧化行为。结果表明，在NaCl盐膜的作用下，铝青铜中的铝较铜先腐蚀，所形成的氧化膜结构疏松，易开裂和剥落，从而加速铝的氧化过程。此外，还讨论了NaCl加速铝青铜氧化的机制。

| Abstract: | The oxidation behavior of aluminum bronze coated with a NaCl film was studied by means of metalloscopy,XRD,SEM/EDS and thermogravimetry.The results show that because of the effect of NaCl film the aluminum will be eroded earlier than the copper in aluminum bronze and the oxide film produced will be loose and easy to crack and spall,with the oxidation of aluminum bronze accelerated.In addition,the mechanism for NaCl film to accelerate the oxidation of aluminum bronze was discussed,too. |
