Tribological Properties of TiAI-Ti_3SiC_2 Composites

The tribological properties of TiAl-Ti_3SiC_2 composites （TMC） against Si_3N_4 ceramic ball pair at room temperature were investigated through the determination of friction coefficients and wear rates, and the morphologies and compositions of wear debris, worn surfaces of TMC and Si_3N_4 ceramic bal...

Zusammenfassung:	The tribological properties of TiAl-Ti_3SiC_2 composites （TMC） against Si_3N_4 ceramic ball pair at room temperature were investigated through the determination of friction coefficients and wear rates, and the morphologies and compositions of wear debris, worn surfaces of TMC and Si_3N_4 ceramic ball were analyzed. The experimental results showed that TMC with 15wt% Ti_3SiC_2 exhibited relatively excellent tribological properties. The solid-phase self-lubricating tribo-layers formed on the worn surfaces of both TMC with 15wt% Ti, SiC, and Si,NA ceramic ball, which was beneficial to the lower friction coefficient and wear rate.
