    • A diamond-like carbon film with a nano-undulated surface is provided to reduce the humidity dependence of friction coefficient due to the characteristics of the nano-undulated surface suppressing tribo-chemical reaction in the transition layer. A diamond-like carbon film has a nano-undulated surface which is formed on a nano dot pattern of a substrate, with RMS surface roughness of 5nm to 50nm. The nano dot pattern is made of metal selected in the group consisting of nickel, cobalt, chrome, iron, zinc, copper, gold, silver, molybdenum, palladium and platinum, and its diameter is 20nm to 800nm. The diamond-like carbon film with the nano-undulated surface is formed by RF-PACVD(Radio Frequency-Plasma Assisted Chemical Vapor Deposition) using methane gas as reaction gas.
    • 提供具有纳米波纹表面的类金刚石碳膜,以降低由于纳米波纹表面的特性而导致的摩擦系数的湿度依赖性,从而抑制过渡层中的摩擦化学反应。 类金刚石碳膜具有形成在基板的纳米点图案上的纳米波状表面,RMS表面粗糙度为5nm至50nm。 纳米点图案由选自镍,钴,铬,铁,锌,铜,金,银,钼,钯和铂的金属制成,直径为20nm至800nm。 具有纳米波状表面的类金刚石碳膜通过使用甲烷气体作为反应气体的RF-PACVD(射频等离子体辅助化学气相沉积)形成。
