英文摘要	In this paper, the effect of the complex condition with high temperature and vacuum on the tribological properties of NiCrMoAl-Ag-CaF₂/BaF₂ solid-lubricating composite has been investigated. It presents that this composite displays the excellent tribological properties in vacuum than in air fromroomtemperature to 800 °C. In vacuum, the friction coefficients are around or below0.20 and superior to that in air. Besides, the wear rates in vacuumare at least one order ofmagnitude lower than those tested in air. They can be divided into three stageswith the temperature (10⁻⁷ mm³/Nm at room temperature and 200 °C, 10⁻⁶ mm³/Nm between 400 and 600 °C, and 10⁻⁵ mm³/Nm at 800 °C). Also, the surface oxidation behavior and the lubrication characteristics of solid lubricants (Ag and fluorides) in vacuum are clarified and related to the tribological properties.
