| 摘 要： | 利用多功能微弧氧化电源，采用目前工艺较为成熟和应用最广泛的电参数对TC4钛合金进行微弧氧化，并在电解液中添加不同浓度的纳米二氧化锆，对比微弧氧化膜层的微观形貌和综合力学性能，探究纳米二氧化锆对膜层的影响。实验结果表明，随着纳米二氧化锆浓度的增加，膜层厚度几乎不发生变化，但膜层的成分和含量发生改变：膜层中出现板钛矿相，且含量不断增加。当纳米二氧化锆浓度为2 g/L时，膜层的粗糙度相比未添加纳米二氧化锆时大幅下降，膜层耐磨性能最好，且此时膜层表面微孔直径最小且尺寸均匀，耐腐蚀性能最佳。

| Abstract: | With the multifunctional micro-arc oxidation power source, the micro-arc oxidation was conducted on TC4 titanium alloy through the treatment with the mature and widely-used electrical parameters. Nano-zirconia of different concentrations was added into the electrolyte to investigate the variation of microstructure and comprehensive mechanical properties of the micro-arc oxidation film. The influence of nano-zirconia on the film was discussed. Results show that with increasing the nano-zirconia concentration, the film thickness barely changes, but the composition and component concentration of the film differ: the brookite phase appears in the film, and its concentration is increasing. When the nano-zirconia concentration is 2 g/L, the roughness of the film layer is greatly reduced, compared with that without nano-zirconia addition, and the wear resistance of the film layer is optimal. In addition, the micropore diameter on the layer surface is the smallest and uniform, and the corrosion resistance is optimal. |
