Study on mechanism of extremely low friction of thin carbonaceous films and their applications

为了实现极低的摩擦，制备了纳米周期多层膜和纳米复合膜等纳米结构碳膜。用透射电子显微镜等表面分析方法对沉积薄膜的结构和成分进行了评价，并与所评价的纳米级力学性能进行了比较。在此基础上，制备了结合碳和多种金属的多层膜和纳米复合膜，并研究了膜结构与边界润滑性能的关系。此外，在聚α-烯烃与添加剂的边界润滑下，含钴、镁、钛的碳基纳米复合膜表现出极低的摩擦力。

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.
