摘要/Abstract

摘要： 采用活化溅射方法，在不同溅射电压条件下，在NiTi形状记忆合金表面成功制备出了纳米TiO2生物薄膜.采用台阶轮廓仪和拉曼光谱仪研究溅射电压对薄膜厚度和晶体结构的影响，并对NiTi合金覆膜前后在37℃模拟人体体液中的耐腐蚀性能进行了评价.结果表明，在本实验条件下薄膜为锐钛矿结构，薄膜表面均匀，其主要成分为纳米尺寸的TiO2；TiO2薄膜明显改善了NiTi合金在37℃模拟人体体液中的耐腐蚀性能.

关键词: NiTi形状记忆合金, 活化溅射, TiO2薄膜, 溅射电压

Abstract: Based on different sputtering voltage conditions， nanometer titanium dioxide biofilm was prepared on NiTi shape memory alloy surface by the activation sputtering method. The influences of the sputtering voltage on the thickness of the film and crystal structure were studied by the step profiler and Raman spectrum. The corrosion resistance of the NiTi alloy and TiO2coated NiTi alloy was evaluated in simulated body fluid at 37℃， respectively. Results showed that under the condition of this experiment the thin film was anatase structure， and the major constituent was nanometer titanium dioxide. The titanium dioxide thin films effectively improved the corrosion resistance of the NiTi alloy in simulated body fluid at 37℃.

Key words: NiTi shape memory alloy, activation sputtering, TiO2 thin films, sputtering voltage
