Dry-sliding tribological performance of in-situ Fe₃Al-20 wt.%Al₂O₃, (4 wt.%Cr)/Fe₃Al-20 wt.%Al₂O₃, and (4 wt.%Cr, 5 wt.%Mo)/Fe₃Al-20 wt.%Al₂O₃ composites, produced by mechanically induced self-propagating mechanism and plasma-activated sintering, was investigated against Inconel718 from 25℃ to 800℃ under air/argon atmosphere. It can be found that (4 wt.%Cr, 5 wt.%Mo)/Fe₃Al-20 wt.%Al₂O₃ composite exhibits more excellent comprehensive tribological properties with the friction coefficient decrease nearly 67% compared to Fe₃Al-20 wt.%Al₂O₃ composite above 350℃ due to the balance between strength and lubricity. At 800℃, the dominant wear mechanism is oxidation wear under air condition, whereas under argon atmosphere, the actual wear mechanism is mainly transferred to microploughing.
