September 2011 Abstract: Titania films with nano-sized pores were prepared on the NaOH-HCl pretreated NiTi alloy substrate by sol-gel method. A crack-free film is obtained for the sample with a dense inner layer and a porous outside layer (sample TC1+1). The X-ray diffraction shows that the titania films are composed of anatase, and a little Ni4Ti3 phase in the heat treated substrate is also detected......
