- 摘要:
- 选用 Ti-6Al-4V 钛合金作为基体在环保型电解液中制备阳极氧化膜，然后分别浸没在沸水、氟锆酸铵溶液、乙酸钙溶液中对阳极氧化膜进行封闭处理。采用扫描电镜、能谱仪和 X 射线衍射仪表征和分析未封闭及封闭处理后阳极氧化膜的微观形貌、化学成分与物相结构，并配制酸性氯化钠溶液作为腐蚀介质，研究未封闭及封闭处理后阳极氧化膜的耐腐蚀性能。结果表明：与未封闭阳极氧化膜相比，在沸水、氟锆酸铵溶液、乙酸钙溶液中封闭处理后阳极氧化膜中微孔数量减少，化学成分发生变化，耐腐蚀性能进一步提高，但封闭处理未影响阳极氧化膜的物相结构。在乙酸钙溶液中封闭过程中发生化学反应，生成水合二氧化钛、氢氧化钛、氢氧化钙和钛酸钙等多种产物，达到协同封闭效果，赋予封闭处理后阳极氧化膜良好的表面致密性，其耐腐蚀性能好于在沸水、氟锆酸铵溶液中封闭处理后阳极氧化膜，对钛合金的防护作用更强。
- Abstract:
- ： The anodic oxide film was prepared on Ti-6Al-4V titanium alloy from environmentally friendly electrolyte ， and then it was sealed by immersing in boiling water ， ammonium fluozirconate solution and calcium acetate solution. The microstructure ， chemical composition and phase structure of unsealed and sealed anodic oxide films were analyzed by scanning electron microscopy ， energy disperse spectroscopy and X-ray diffractometer. Furthermore ， the corrosion resistance of unsealed and sealed anodic oxide films was studied using acid sodium chloride solution as the corrosion medium. The results show that ， compared with unsealed anodic oxide film ， the anodic oxide films after sealing treatment in boiling water ， ammonium fluozirconate solution and calcium acetate solution have fewer micropores ， the chemical composition changes and the corrosion resistance is further improved. However ， sealing treatment has no effect on the phase structure of the anodic oxide film. Various products such as hydrated titanium dioxide ， titanium hydroxide ， calcium hydroxide and calcium titanate are generated by chemical reaction during the sealing process in calcium acetate solution to achieve synergic sealing effect. The anodic oxide film after sealing treatment in calcium acetate solution has good surface densifi cation ， and its corrosion resistance is better than that of the anodic oxide film after sealing treatment in boiling water and ammonium fluozirconate solution ， and the protective effect on titanium alloy is stronger.
