| Summary: | The Al<sub>2</sub>O<sub>3</sub>/Ti(C,N) ceramic material added micron ZrO<sub>2</sub> whisker and nano coated CaF<sub>2</sub>@Al(OH)<sub>3</sub> powder was fabricated. The micron ZrO<sub>2</sub> whisker was for the toughening and reinforcing phase and the nano coated CaF<sub>2</sub>@Al(OH)<sub>3</sub> powder was the lubricant. For obtaining a ceramic material with optimal comprehensive mechanical properties and friction properties, the influences of different compositions of the ZrO<sub>2</sub> whisker and nano coated CaF<sub>2</sub>@Al(OH)<sub>3</sub> powder on the microstructure and mechanical properties were analyzed, respectively. The result demonstrated that as the addition of the ZrO<sub>2</sub> whisker was 6 vol% and the addition of the nano coated CaF<sub>2</sub>@Al(OH)<sub>3</sub> powder was 10 vol%, the optimal self-lubricating ceramic material had optimal mechanical properties. The hardness of the ceramic material was 16.72 GPa, the flexural strength was 520 MPa and the fracture toughness reached 7.16 MPa·m<sup>1/2</sup>. The formation of the intragranular structure, whisker toughening and the phase transition of ZrO<sub>2</sub> were the main mechanisms.
