- 摘要:
- 设计并加工了铝 5A06 的热处理、氩弧焊以及电子束焊工艺样件。分别对 3 种样件进行了 SEM 形貌分析、能谱分析，分析结果表明 3 种处理方法均在样件表面生成了氧化膜，氩弧焊、电子束焊样件在热影响区、焊缝区形成了第二相。首先采用 30% 的盐酸去除热处理、氩弧焊以及电子束焊样件表面的氧化膜，然后按照 1 ∶ 3 的比例采用 HF 酸和 HNO 3 的混合酸对 3 种样件进行酸侵蚀，最后对其进行化学氧化处理，结果表明 3 种样件表面的化学氧化膜色泽基本一致。
- Abstract:
- ： The heat treatment ， argon arc welding and electron beam welding of Al 5A06 samples were designed and processed. SEM morphology analysis and energy spectrum analysis were carried out on the three samples ， and the analysis results showed that the oxide film was generated on the surface of the samples by the three treatment methods ， and the second phase was formed in the heat-affected zone and weld zone of the argon arc welding and electron beam welding samples. Firstly ， 30% hydrochloric acid was used to remove the oxide film on the surface of the three samples ， and then HF acid and HNO 3 acid was mixed by 1 ∶ 3 volume ratio to corrode the samples ， the chemical oxidation treatment was lastly carried out on the samples ， the results showed that the color of the oxide film on the three kinds of samples was basically the same.
