考察金属托槽表面掺氮TiO2-xNx薄膜的生物摩擦磨损性能。采用射频磁控溅射法在不锈钢金属托槽原材料表面制备掺氮TiO2-xNx薄膜,通过扫描电子显微镜（SEM）和X射线衍射（XRD）技术分析薄膜微观结构,利用UMT-2MT型摩擦磨损试验机考察薄膜的体外生物摩擦磨损性能。结果表明所制备的掺氮TiO2-xNx薄膜为锐钛矿结构,纳米量级,薄膜均匀致密;在干摩擦及人工唾液和Hank’s溶液的润滑条件下,掺氮TiO2-xNx薄膜均表现出良好的抗磨损低摩擦性能。
To evaluate the biologic wear properties of the nitrogen-doped TiO2-x Nx films on brackets. To pro duce the nitrogen-doped TiO2-x Nx films on the surfaces of stainless steel metal brackets by the method of radio frequency magnetron sputtering. The microstructure and the biologic wear properties of the nitrogen-doped TiO2-x Nx films were observed by scanning electron microscopy, X-ray diffraction and type UMT-2MT friction abrasion testing machine. Results： showed that the microstructure of the nitrogen-doped TiO2-x Nx films is sharp titanium mineral, nanometer level and uniformly dense structure; the nitrogen-doped TiO2-x Nx films perform good wear and low-friction properties under these conditions which are dry friction, artificial saliva so- lution and Hank＇s solution.
