钛合金表面阳极化处理对钛合金／复合材料胶接性能的研究

通过碱性阳极化方法NaTESi处理钛合金，碳纤维复合材料胶接试件中钛合金的表面。主要研究了阳极化前碱洗酸洗、阳极化过程中的电压、温度、时间以及该方法与喷砂法结合对处理后的钛合金胶接试件胶接性能的影响。结果表明：钛合金阳极化前的碱洗酸洗能提高钛合金／碳纤维复合材料胶接试件的粘接强度，阳极化过程中，电压在8-12V，温度在15。25％，时间在15．25min之间时处理出的钛合金所制成的胶接试件有较好的湿热耐久性能；喷砂法与NaTESi阳极化法配合处理钛合金表面，可使钛合金，碳纤维复合材料胶接试件湿热耐久性能得到进一步的提高。

Study on the Effects of the Anodization Surface Treatment on the Bonding Properties of Titanium Alloy/ Composite Materials

The surface of titanium alloy bonded with carbon fiber composite was treated by the alkaline anodization treatment of NaTESi. The influence of alkali and acid wash of titanium alloy before anodizing process, the different anodizing voltage, temperature, time and the treatment of NaTESi combined with sandblast on the adhesion properties of the titanium alloy/carbon fiber composite joint was studied. The results showed that alkali and acid wash could improve the shear strength of the joint, and when the anodizing voltage was 8~12V, the anodizing temperature was 15- 25~C, and anodizing time was 15-25min, the hydrothermal durability of the joint could be improved, and it could get further improvement through the titanium alloy surface treatment by the NaTESi anodization combined with sandblast.
