Abstract

The alloys are based on Ti-45Al-5Nb, Added different contents of TiC, Y2O3 and 62% BaF2-38%CaF2 to prepared new TiAl-based self-lubricating Alloys with excellent mechanical properties, excellent tribological properties and light weight. Investigated flexural strengths, fracture toughness, hardness, and densities of different compositions TiAl based self-lubricating alloys, as well as the friction and wear characteristics at 600°C. The results show that the mechanical properties, tribological properties and physics of the new TiAl-based alloys are better with 5% TiC, 0.25% Y2O3, and 13% (62% BaF2-38%CaF2). The wear mechanism of the alloys is adhesive wear.
