This paper investigates the effects of TiO2 addition on the composition， microstructure， mechanical properties， and wear resistance of ZTA/ZMn13 composite materials. The results show that the density of ZTA ceramic increases first and then decreases with increasing firing temperature and TiO2 addition. When the firing temperature is 1 600 ℃ and the TiO2 addition is 2 wt.%， the ZTA ceramic has the best comprehensive properties： the relative density reaches the highest value of 98.73%， the flexural strength is （429.60±24.56） MPa， the Vickers hardness （HV） is （1691.73±120.65） N/mm2， the fracture toughness is （7.24±0.38） MPa·m1/2. At 1 450 ℃， the contact angle between ZTA and ZMn13 melt decreases with increasing TiO2 addition， because the TiO2 on the surface of ZTA is connected to the ZMn13 substrate through Ti—O—Fe bonds， thus improving the interfacial wettability between ZTA and ZMn13 substrate. The ZTA ceramic particles prepared as a three-dimensional porous preform are cast at 1 450 ℃ to prepare the ZTA/ZMn13 composite materials. The flexural strength of the material increases first and then decreases with increasing TiO2 content in ZTA， reaching a maximum value of 273.63 MPa when TiO2 content is 2 wt.%. Compared with the ZTA/ZMn13 composite materials prepared without TiO2 （201.72 MPa）， its strength is increased by 35.63%， and its wear resistance is improved by 21.98% under three-body wear conditions.
