Abstract
The dry-sliding tribological behaviors of Ti–46Al–2Cr–2Nb intermetallics and its composites with 20 and 40 vol% in situ formed TiB2 produced by hot press sintering process were investigated. Also, the microstructures and mechanical properties of the three materials were examined. With the increase of TiB2 amount, the hardness and wear resistance ascended. The enhanced wear resistance can be attributed to the higher hardness and the load-carrying role of TiB2. The friction coefficient was irrespective of TiB2 content. The wear mechanism of the materials was dominated by fatigue wear and delamination.
