【 摘 要 】

Fe was introduced into TiC-2Mo2C-8Ni-20WC-8Co cermets materials. Content of Co and Fe were 8-X and X respectively, and X was 0%, 2%, 4%, 6%, 8%. Density, bending strength and impact toughness of the material were tested. Results showed that it was feasible to add Fe into the material as binder to partially replace Co. Comparing with the specimen containing 0%Fe, properties of the specimen containing 6%Co and 2%Fe had not slashed. Its density, bending strength and impact toughness were 6.783g/cm3, 847.7MPa and 16.1J/cm2 respectively.
