摘要

LaPO_4/Al_2O_3 composites were fabricated by spark plasma sintering. The effects of LaPO_4 contents on the mechanical properties of the composites were investigated. The bending strength and fracture toughness can reach the maximum value of 568.2 +30 M Pa and 4.8 + 0.5 MPa·m~(1/2) for the composite with 16.4 vol% LaPO_4 addition, respectively. The elastic moduli and hardness of the composites decreased with increasing LaPO_4 content. Furthermore, the experimental results show that the composites can be machined by a tungsten carbide drill as the LaPO_4 volume fraction is higher than 34.4 vol%.
