摘　　要：利用溶胶－凝胶法（Ｓｏｌ－ｇｅｌ）制备了单层及双层ＴｉＯ２薄膜材料．分析结果表明所制薄膜主要由非晶ＴｉＯ２纳米颗粒组成．单层及双层ＴｉＯ２与钢球及Ｓｉ３Ｎ４陶瓷球对摩在轻载荷（３Ｎ）下具有良好的减摩与抗磨性能，与钢球对摩时失效循环次数分别为３７６和１８５６，与陶瓷球对摩时失效循环次数分别为２２８０和２３４３．玻璃基片主要发生脆性断裂及严重的磨粒磨损；TiO 2 thin film was prepared by sol gel method. XPS, XRD and EPMA results indicate that the film is mainly composed of amorphous TiO 2 nanoparticles. The friction coefficient of the film sliding against GCr15 steel and Si 3N 4 is 0.16￣0.18 and 0.16￣0.28, for one layer and two layer film, respectively; that for microscope slide is 0.78￣0.94. The film also has high antiwear life in sliding against GCr15 steel and Si 3N 4. Microscopic observation of the film surface and worn surfaces indicates that brittle fracture and sever abrasive wear dominated wear of glass slide; while plastic deformation and slight abrasive wear governed wear of TiO 2 thin film.
