【英文摘要】Antiwear thin film is considered to be very important in the field of protecting materials. Nano films, composite films and self-assembled monolayers prepared on the surface of inorganic films can enhance friction-reducing and antiwear properties of inorganic films. In the present research, the nano-scale inorganic films such as MoS2, TiO2 were prepared by PVD and Sol-Gel process. Some low surface energy lubricants such as Phosphazenes, ionic liquid were synthesized, and deposited or assembled to the surfaces of the prepared inorganic films, with the formation of inorganic-organic binary film. The metal matrix nanocomposite coatings were prepared by electrodeposition. Results show that the nano-scale inorganic films such as MoS2, TiO2 exhibit low friction and small wear. The synthetic phosphazenes and ionic liquid show good thermal stability and anti-wear ability. The differences in their lubricating mechanisms of the compounds were related to the differences of their chemical structures. Heat treatment effectively improved the scratch resistance and friction and wear properties of inorganic-organic binary films. The co-deposited SiC, Si3N4, CNTs, MoS2 nano-particulates greatly enhanced mechanical properties, corrosion resistance and tribological properties of the nanocomposite coatings. These results obtained in this project is useful to develop new materials for the lubrication of space and information industries.
