    摘要:

    通過固相反應法合成了一維二硒化鈮納米材料，用X射線衍射（XRD）儀和透射電子顯微鏡（TEM）表征了該一維納米材料的形貌特征。將二硒化鈮納米線按不同質(zhì)量分數(shù)配比加入潤滑油，采用UMT-2型微摩擦磨損試驗機評價其摩擦學性能；用掃描電子顯微鏡（SEM）觀察了磨痕表面形貌；探討了含NbSe2納米材料潤滑油的減摩抗磨機理。結(jié)果表明，含有 NbSe2 添加劑的潤滑油可有效減小摩擦系數(shù)；特別是高載高速時，隨著NbSe2質(zhì)量分數(shù)的增加，摩擦系數(shù)數(shù)減小，磨損量降低且提高了潤滑油的承載能力。探討后發(fā)現(xiàn)主要是由其獨特的閉合結(jié)構(gòu)、潤滑膜的形成、納米材料的填充自修復作用機制共同作用的效果

    Abstract:

    One dimensional nanostructure NbSe2 was synthesized by a solid-phase reaction method. And the micrographite was characterized by XRD and TEM. Adding different mass fraction ratios of NbSe2 to the lubricant, their tribological properties were evaluated using UMT-2 micro-tribometer. The worn surface morphologies were observed by SEM. And the lubricant tribological mechanism with NbSe2 adding was explored. The results show that lubricants containing the NbSe2 additives can effectively reduce the friction coefficient, especially under high load and high speed conditions. As NbSe2 increases, the friction coefficient decreases, the wear decreases and the carrying capacity of lubricating oil is improved. It is found that the effects are mainly produced by the unique closed structure, the lubricant film formation and nano-materials self-repair together.
