| 摘 要： | 采用溶胶-凝胶法在普通玻璃基底上制备了纯TiO2和Cu掺杂的TiO2(Cu-TiO2)纳米结构薄膜,利用X射线光电子能谱(XPS)、原子力显微镜(AFM)、粉末X射线衍射(XRD)及UMT-3摩擦磨损试验机考察了Cu掺杂量对薄膜组成、结构、表面形貌及摩擦学性能的影响.结果表明,相比于纯TiO2薄膜,Cu掺杂TiO2纳米薄膜平整、均匀,具有较好的耐磨减摩性能.Cu掺杂量的多少直接影响Cu-TiO2薄膜的减摩抗磨性能,当Cu掺杂量为5%(摩尔分数)时,Cu-TiO2膜具有最佳的耐磨寿命和最低的摩擦系数.

| Abstract: | Undoped TiO2 and Cu-doped TiO2 (Cu-TiO2) nano-structured thin films were prepared by a sol-gel process on glass substrates. We investigated their structures, surface morphologies, and tribological properties by X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), X-ray diffraction (XRD), and friction and wear testing using a UMT-3 tester. We found that the prepared Cu-TiO2 films were smoother and more uniform than the undoped TiO2 films and they had better friction-reducing and anti-wear properties. The amount of Cu dopant directly affects the tribological performance of the doped TiO2 film. The 5%(mole fraction) Cu-TiO2 film possesses the longest wear life and the lowest friction coefficient. |
