Surface treatment on titanium sheets by NaTESi anodization at constant voltage is conducted to improve the bonding properties of TA2/polyetheretherketone (PEEK) in TA2/Cf/PEEK laminates. The effects of technical parameters (such as voltage, time and temperature) on the single lap joint shear strength and the surface roughness of TiO2 film are investigated by an orthogonal test. It demonstrates that the most important factor affecting the bonding properties is time. Longer anodization times resuted in lower surface roughness, which contributed to inferior bonding properties. Properties of the TA2 laminate are investigated by XRD and SEM, and the results show that the optimized process which is favorable for the increase of the bonding strength is as follows: anodizing voltage 10 V, anodizing temperature 35℃ and anodizing time 10 min. The surface roughness treated by this method is 1.34 μm and the nano-particles morphology appeares, which the size of the particles is about 100-200 nm. The single lap joint shear strength with these parameters could reach 19 MPa. The resistance to delamination between the titanium sheet and PEEK in this optimized process is measured in a double cantilever beam test. The average energy release rate of the TA2/PEEK interface which was prepared by the method of NaTESi anodization is 188.1 J/m2, which showes an increase of 103.1% compared with the untreated ones. The results indicate that the anodizing process markedly enhance the delamination resistance of TA2/PEEK bonding interface.
