采用水热法在Ti和Ti-Nb基体上制备了锐钛矿型TiO 2薄膜，研究了薄膜的结晶性和表面形貌。用H2 O2/HCl或H2 O2/HNO 3溶液对衬底进行化学处理，制备了类无定形TiO 2。在高压釜中用去离子水或NH3水溶液对所得膜进行水热处理。合成的锐钛矿型TiO 2薄膜具有较高的结晶度和矩形形貌。以Ti-Nb合金为基体可以获得（Ti，Nb）O2薄膜。
The hydrothermal synthesis of anatase-type TiO2films on Ti and Ti–Nb substrates was examined with a focus on crystallinity and surface morphology of the films. The substrates were chemically treated with H2O2/HCl or H2O2/HNO3solution to prepare amorphous-like TiO2. The hydrothermal treatment of the resultant films was performed in an autoclave with deionized water or NH3aqueous solution. The synthesized anatase-type TiO2films showed high crystallinity and rectangular morphology. The (Ti, Nb)O2film could be obtained by using Ti–Nb alloys as substrates.
