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.
