| 摘要: |
| 针对传统钝化工艺环境危害大的问题，优选了紫铜表面钛盐钝化工艺参数。通过变化钝化温度及时间，分析了成膜机理。结果表明：对于无氟钛盐铜钝化液，在紫铜材料表面，钝化温度25℃，pH为2.0～2.5，钝化时间为60s的条件下可得到耐腐蚀性良好并具有金属光泽的铜本色钝化膜，成膜过程存在二次成膜过程。 |

| Abstract: |
| The parameters of passivation using titanium bath on the surface of red copper was researched to deal with the huge environmental impact caused by the traditional passivation. The film formation mechanism was also discussed. The result shows that, the film which was formed under the parameters that the temperature was 25℃，the pH was 2.0～2.5, the passivate time was 60s, had the best anti-corrosion properties. The second film forming existed during process of the film formation. |
