【英文摘要】For meeting the demands of the national space technology for solid lubricating materials with high reliability, long wear-life and superlow friction coefficient, the tribological properties of composite carbon film in space environment have been investigated systematically, and the influence of special space conditions such as high vacuum, alternating changes of high and low temperature, intense irradiation, atomic oxygen and strong oxidizing agent etc,on the microstructure and tribological properties of the films have been studied to reveal the relations between the film microstructure and tribological properties in space environment. Meanwhile, the damage/failure models of the carbon films in space environment have been established. Based on the above researching results, nanocrystalline/amorphous novel nanostructural carbon films with high reliability, long wear-life and superlow friction coefficient have been developed by designing the film mirostructure and controling the film component. The application researches of the films in high-tech industries have also been carried out, and well results have been obtained. The major research achienements of the project have great theoretical significances and application values to resolve the key lubricating problems that restrict the development of national space industry.Under the financial support of the project, 24 research papers have been published, in which 18 papers are indexed by SCI. Furthermore, 6 national invention patents are applied, and 1 sceond prize of Gansu Privincial natural science is won. In conclusion,all the preconcerted research contents in the project are successfully completed.
