| 摘 要： | 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。 |
| 关 键 词： | 射频磁控溅射法 掺氮TiO2-xNx薄膜 生物摩擦磨损性能 |

| Abstract: | To evaluate the biologic wear properties of the nitrogen-doped TiO2-xNx films on brackets.To produce the nitrogen-doped TiO2-xNx 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-xNx 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-xNx films is sharp titanium mineral,nanometer level and uniformly dense structure;the nitrogen-doped TiO2-xNx films perform good wear and low-friction properties under these conditions which are dry friction,artificial saliva solution and Hank’s solution. |
| Keywords: | radio frequency magnetron sputtering nitrogen-doped TiO2-x Nx films biologic wear properties |
