摘要
分别以铬酸阳极氧化(CAA)和氢氧化钠阳极氧化(SHA)两种方法,处理用于钛合金/钛合金胶接试样的TB8钛合金表面,通过拉伸剪切试验测量了钛合金/钛合金胶接试样的剪切强度,分析了氧化时间和电压对钛合金粘接强度的影响。结果表明:电压10V时,CAA方法处理10~15min、SHA方法处理15~20min的钛合金均能获得很高粘接强度;氧化膜层太薄与太厚均不利于提高钛合金/钛合金胶接剪切强度。
It adopts Chromic Acid Anodize( CAA) and Sodium Hydroxide Anodize( SHA) respectively to treat the surface of TB8 titanium bonded with TB8 titanium,analyzes the shear strength of titanium / titanium cementing sample at different voltages and treatment time through lap shear tests. The results show that the shear strength is excellent when the specimens are anodized at 10V by CAA treatment for 15 ~ 20min or by SHA treatment for 10 ~ 15min,the too thick or too thin samples with oxidation coatings do not improve the bonding properties.
