| 中文摘要 | High temperature self-lubricating composites Ni3Al–BaF2–CaF2–Ag–Cr were fabricated by powder metallurgy technique. In this paper the effect of Cr content on tribological properties at a wide temperature range starting from room temperature to 1000 1C was investigated. It was found that Ni3Al matrix composite with 20 wt% Cr exhibited low friction coefficient of 0.24–0.37 and a wear rate of 0.52–2.32 10 4 mm3 N 1 m 1 . Especially at 800 1C it showed the lowest friction coefficient of 0.24 and a favorable wear rate of 0.71 10 4 mm3 N 1 m 1 . This implied that 20 wt% Cr was the optimal Cr content and its excellent tribological performance could be attributed to the balance between strength and lubricity. |
