Abstract	Self-lubricating materials are particularly suitable used in the advanced mechanical motion systems with extreme conditions such as high temperature, high-speed and heavy-loading. In this paper, a high-temperature self-lubricating composite, Fe₃Al with embedded Ba_0.25Sr_0.75SO₄ solid lubricant are prepared by hot-pressed sintering technique. Meanwhile, the effects of Ba_0.25Sr_0.75SO₄ fraction on microstructure, hardness and high-temperature tribological properties of the composites are investigated. The results show that the high-temperature tribological properties of the Fe₃Al alloy are greatly improved by the addition of Ba_0.25Sr_0.75SO₄, and the wear mechanism transforms from fatigue wear to abrasion wear.
