Wear Behavior of Al2O3/Ti3AlC2-MAX Composites at Elevated Temperatures
This paper investigates the effect of Ti<sub>3</sub>AlC<sub>2</sub>-MAX phase addition as a solid lubricant to Al<sub>2</sub>O<sub>3</sub>. The composites were prepared using powder metallurgy and consolidated by Spark Plasma Sintering (SPS). The influence of Ti<sub>3</sub>AlC<sub>2</sub> addition on phase composition and mechanical and tribological properties was evaluated. The use of MAX phase allows for the fabrication of sintered materials characterized by high density, a hardness close to 2000 HV5, and a fracture toughness of 5.5 MPa*m<sup>0.5</sup> for the sample containing 10 wt.% Ti<sub>3</sub>AlC<sub>2</sub>. Moreover, a significant reduction in wear of the composites was observed for friction tests conducted at 700 °C compared to the unreinforced sample. The research demonstrates that Ti<sub>3</sub>AlC<sub>2</sub> can serve as a solid lubricant and exhibits the best performance at high temperatures.
