摘要

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 TiB ₂ content. The wear mechanism of the materials was dominated by fatigue wear and delamination.
