Development of Superlubricity Materials Based On Incommensurate Theory

In order to develop superlubricity materials based on incommensurate theory，we investigated the subject under the following three heads：(1)synthesis of MoS锡D22 IIE D2 superlubricant material by mechanical alloying method；(2)investigation of possibly of super-low friction material by ion-beam-assisted deposition method and(3)development of ultra-high resolution displacement measurement system by optical fiber interferometerial and(3)development of ultra-high resolution displacement measurement system by operial by ion-beam-assisted deposition method and(3)development of ultra-high resolution displacement measurement system by。The friction coefficient of MoS锡D22文件D2 compacts was decreased below 0.05 in a vacuum.2。We clarified the formation condition of preferred oriented TiN film by ion-beam-assisted deposition method。The mechanical properties of(111)and(200)strong preferred films were estimated.3。We clarified tribological properties of C-N films prepared by ion-beam-assisted deposition method。It was clarified that the wear resistance of C-N films were far superior to DLC films.4。We fabricated the high-resolution displacement system by optical fiber interferometer.The resolution of the displacement was increased and the value was reached up to 0.3 nm。
