摘 要：The tribological properties of TiAl-Ti3SiC2 composites（TMC） against Si3N4 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 Si3N4 ceramic ball were analyzed. The experimental results showed that TMC with 15wt% Ti3SiC2 exhibited relatively excellent tribological properties. The solid-phase self-lubricating tribo-layers formed on the worn surfaces of both TMC with 15wt% Ti3SiC2 and Si3N4 ceramic ball, which was beneficial to the lower friction coefficient and wear rate.
