摘要
本项研究确定了防止钛合金与其它活泼金属接触时发生电偶腐蚀,防止粘结,提高其表面硬度,减少摩擦磨损的脉冲微弧阳极氧化工艺。微弧阳极氧化在L(含硫化合物)、T(含磷化合物)及若干添加剂的混合电解液中进行。由脉冲电源供电。高压、高热的微弧使零件表面发生等离子体放电现象,形成2μm-15μm致密的、高绝缘的氧化膜层。具有抗腐蚀、防粘结的功能;同时,钛合金的表面硬度得到大幅度提高。
This research confirmed Ti - alloy anodic oxidation technology which prevents Ti - alloy from electric double corrosion and adhering under contacting with other metals and increases the hardness of surface and decreases abrasion. The anodic oxidation process is in mixed electrolyte solution with some additives, such as L, T. The pulse current is supplied. The high voltage makes micro - arc oxidizing on the surface of the component , and then 2μn- 15μm dense membrane formed of which is high insulation , corrosion resistant, adhesion - prevented, and surface hardness of Ti - alloy obviously increased.
