Preparation and Friction Feature of TiAl-Based Wear-Resisting Self-Lubricating Composite

Abstract:

In this paper, TiAl intermetallic compound superfine powder is prepared through mechanical alloying and heat treatment, of which the content of TiAl intermetallic compound may reach 95%, and TiAl-based wear-resisting composite are obtained via hot-press sintering process and addition of solid lubricant, furthermore the preparation process, microstructure and friction and wear property of TiAl-based wear-resisting composite are studied. The experimental results show, the solid lubricant in the composite is stable and doesn’t react with components of TiAl-based materials. The friction coefficient of the composite will gradually decrease with the increase of the amount of solid lubricant CaF2+BaF2, and the minimum value 0.386 will appear when amount of addition is 15%, where the adhesive wear of materials decreases. When the amount of the addition is 15%, the wear rate is up to the lowest, but it’ll increase instead in case that the amount of addition is more than 15%.
