Abstract:The vertically aligned highly ordered TiO2 nanotube arrays were fabricated by potentiostatic anodization of biologic Ti alloys(TLM) and pure Ti substrates, followed by annealing at 480 and 550 ℃ for 6 h. High-resolution scanning electron microscopy (SEM) was applied to characterize the original films. The phase of the film was characterized by XRD. The interfacial adhesion and bond strength between thin films coating and substrate were tested by scratch method. The results show that the films on the TLM alloy have high adhesion strength compared with them on pure Ti.

 

Key words: TiO2; nanotube arrays; titanium alloys; adhesion strength; properties
