成分配比对三元硼化物金属陶瓷Mo2FeB2性能的影响

The Effect of Component on the Properties of Ternary Boride Based Cermets Mo2 FeB2

三元硼化物金属陶瓷Mo2FeB2具有良好的硬度和耐磨性，且可通过原位液相反应生成。但不同的成分配比对生成三元硼化物Mo2FeB2性能的影响很大，本文通过实验，对不同Mo／B原子比的三元硼化物金属陶瓷Mo2FeB2的组织结构和硬度进行了对比研究，试验结果表明，当Mo／B原子比为1．1时，三元硼化物金属陶瓷Mo2FeB2具有较好的组织和性能。

Ternary boride based cermets Mo2FeB2 have satisfactory hardness and wear- resisting , but different component give different effects to the properties of ternary boride based cermets Mo2 FeB2 which produced by in - situ liquid reaction sintering. The structure and hardness of Mo2 FeB2 with different atomic ratio of Mo/B was compared in this article. The results show that the properties of ternary boride cermets Mo2FeB2 are better than others when the atomic ratio of Mo/B equals 1.1.
