研究了采用化学-水热相结合的方法在纯钛表面制备生物惰性氧化膜。用H2 O2/HNO3对纯钛衬底进行化学处理，形成了TiO2凝胶层。然后用分散的NH3/CH3CH(OH)COOH水溶液在453K高压釜中对样品进行水热处理12h。结果表明，成功地在薄膜表面制备了ZrO2-TiO2二元复合薄膜，薄膜中ZrO2的体积分数从衬底到表面逐渐增加。在模拟体液浸泡过程中，梯度氧化锆-二氧化钛薄膜抑制了羟基磷灰石在表面的沉积。
The synthesis of bioinert oxide films on pure Ti surfaces by a combined chemical-hydrothermal treatment was investigated. Pure Ti substrates were chemically treated with H 2 O 2 /HNO 3 to form a TiO 2 gel layer. The specimens were then hydrothermally treated with Zr(OH) 4 dispersed NH 3/ CH 3 CH(OH)COOH aqueous solution in an autoclave at 453K for 12h. As a result, ZrO 2 -TiO 2 composite films were successfully produced on the surface, and the volume fraction of ZrO 2 in the film was found to gradually increase from the substrate to the surface. The graded ZrO 2 -TiO 2 film suppressed the deposition of hydroxyapatite on the surface during soaking in simulated body fluid.
