| Research Abstract |
To realize extremely low friction, nanostructured carbonaceous films such as nanoperiod multilayer films and nanocomposite films were deposited. Evaluation of the structure and composition of the deposited films was performed by surface analysis methods such as transmission electron microscopy and compared with evaluated nanometer-scale mechanical properties. Furthermore, multilayer and nanocomposite films that combined carbon and various metals were deposited, then the relation between the film structure and the boundary lubrication properties was evaluated. Moreover, under boundary lubrication using polyalphaolefin with an additive, carbonaceous nanocomposite films containing Co, Mg or Ti exhibited extremely low friction.
