- 摘要:
- 选取汽车用2036铝合金作基体在草酸电解液中进行阳极氧化，并采用不同方法封孔，表征了封孔前后氧化膜的微观形貌、表面成分及耐腐蚀性能。结果表明，封孔后的氧化膜的微观形貌明显不同于未封孔氧化膜，封孔氧化膜的耐蚀性明显提高，但不同封孔工艺的氧化膜的耐蚀性存在一定差异，铬酸盐封孔氧化膜的耐蚀性优于热水封孔和镍-钴盐封孔的氧化膜。
- Abstract:
- The automobile 2036 aluminum alloy was used as the substrate for anodic oxidation in oxalic acid electrolyte, and the holes were sealed by different methods. The micromorphology, surface composition and corrosion resistance of the oxide film before and after sealing were characterized. The results showed that the microscopic morphology of the sealed oxide film was obviously different from that of the unsealed film. The corrosion resistance of the sealing oxide film was significantly improved, but there were certain differences in the corrosion resistance of the oxide film with different sealing processes. The corrosion resistance of the chromate sealing oxide film was better than that of hot water sealing and nickel-cobalt salt sealing.
