| 摘 要： | 采用离子束沉积技术在医用Ti6Al4V合金表面制备类金刚石薄膜(DLC),利用原子力显微镜、Raman光谱、X射线光电子能谱(XPS)及UMT-2摩擦磨损试验机对薄膜的形貌、结构、摩擦学性能进行表征。采用动电位极化对涂层前后基底的耐腐蚀性能进行测试。结果表明:制备薄膜为类金刚石碳结构,基底偏压对薄膜形貌、结构有较大影响;偏压为-100V时制备的薄膜表面粗糙度低(6.5nm),sp3/sp2比值高,摩擦学性能优异;经DLC膜保护的合金基底耐腐蚀性能获得明显改善。

| Abstract: | Diamond-like carbon(DLC) films were prepared on medical Ti6Al4V alloy by ion beam sputtering deposition technology.The morphology,microstructure and tribological properties of the films were characterized using atomic force microscopy(AFM),Raman spectroscopy,X-ray photoelectron spectroscopy(XPS) and UMT-2 universal micro-tribometer.The corrosion resistance in Hank's solution of the films and the uncoated sample was evaluated by means of potentiodynamic polarization techniques.The results indicate that the c... |
