| 中文摘要: |
| 现代工业的迅猛发展迫使愈来愈多的机械零部件需要在高温下运转，因此高温润滑材料的匹配发展至关重要。在摩擦表面沉积固体润滑薄膜是降低高温下机械装备的摩擦与磨损，提高其使用寿命和可靠性的有效手段。近年来，类金刚石碳（Diamond-like carbon，DLC）薄膜的高温摩擦学得到了广泛研究，并取得了一些重要的进展。大量研究表明，通过适当的元素掺杂可以显著提高DLC薄膜的高温摩擦学性能。首先分别综述了纯碳DLC薄膜、含氢DLC薄膜、Si掺杂DLC薄膜、金属元素掺杂DLC薄膜、元素共掺杂DLC薄膜的高温摩擦学研究进展。通过总结文献中的数据，绘制了各种DLC薄膜的摩擦系数随温度的变化曲线，进而确定了各种薄膜的有效润滑温域。在此基础上，提出了几种有望实现宽温域连续润滑的DLC薄膜新体系，并分析了DLC薄膜的高温润滑失效机理，强调了分子/原子的热扩散和薄膜的热应力在DLC薄膜高温润滑失效中的作用。最后，从提高DLC薄膜自身的高温摩擦学性能和提高DLC薄膜与基材的高温结合性能两个方面，对今后亟待开展的研究工作进行了展望。 |

| The rapid developing modern industry forces more and more mechanical parts to run at high temperature, hence, the matching development of high-temperature lubricating materials is crucial. Deposition of solid lubricating films on the frictional surfaces of machinery is an effective way to reduce friction and wear, and improve its service life and reliability at high temperature. Recently, the tribology of diamond-like carbon (DLC) films at high temperature has been studied intensively, and some important progress has been achieved. Many studies indicate that the tribological properties of DLC films at high temperature can be significantly improved by proper doping. Herein, the currentprogress of high-temperature tribology of pure carbon DLC films, hydrogenated DLC films, Si-doped DLC films, metal-doped DLC films, and co-doped DLC films was first reviewed. By summarizing the data in the literature, the temperature dependence curves of friction coefficients of various types of DLC films were drawn, and the corresponding effective lubrication temperature ranges were determined.Then several novel doped DLC films expected to achieve continuous lubrication in a wide temperature range were proposed, and failure mechanisms of DLC films at high temperature were analyzed, highlighting the role of molecular/atomic thermal diffusion and thermal stress in high-temperature lubrication failure of DLC films. Finally, the future research work is suggested in terms of improving the high-temperature tribological properties of DLC films and the high-temperature adhesion of DLC films to substrates. |
