摘　　要：在Fe基复合材料Fe-1.5Cu-1.8Ni-0.5Mo-1C和Fe-1.5Cu-0.7C中分别添加TiC和WC/TiC颗粒,采用常规混粉与网带烧结工艺制备颗粒增强复合材料,观察和测试材料的显微孔隙形貌、密度、硬度与抗弯强度等性能。结果表明,TiC与Fe-1.5Cu-1.8Ni-0.5Mo-1C和Fe-1.5Cu-0.7C之间的界面结合较WC差,仅添加TiC时,材料性能最差,性能随着TiC含量增加而下降;仅添加WC时,材料性能最优,性能随着WC含量增加而先增后降;同时添加TiC和WC时,材料性能居中,性能亦随着Ti C和WC含量增加而下降。本文试验条件下,在Fe-1.5Cu-1.8Ni-0.5Mo-1C和Fe-1.5Cu-0.7C中添加适量的WC作为增强颗粒是较佳的选择。TiC and WC/TiC were added into Fe-1.5 Cu-1.8 Ni-0.5 Mo-1 C and Fe-1.5 Cu-0.7 C.Composites were prepared by conventionally mixed powder in mesh belt sintering furnace.Material properties were tested including microscopic pore morphology,density,hardness and bending strength.The results show that compared with WC,the interface bonding between TiC and Fe-1.5 Cu-1.8 Ni-0.5 Mo-1 C/Fe-1.5 Cu-0.7 C is poorer.When TiC is added,materials have the worst performance,which declines as TiC content increases.When WC is added,materials have the best performance,which first increases and then decreases with the increasing of WC content.When TiC and WC are added at the same time,materials have the moderate performance,which also declines as Ti C and WC content increases.Under the experiment condition of this paper,adding the right amount of WC to Fe-1.5 Cu-1.8 Ni-0.5 Mo-1 C/Fe-1.5 Cu-0.7 C as reinforcing particles may be a better choice.
