摘要
考察了氧对Ｍｏ２ＦｅＢ２金属陶瓷性能的影响。结果表明：基体中的氧能与硼形成表观像玻璃的Ｂ２Ｏ３杂质，烧结时这些Ｂ２Ｏ３杂质能从基体内迁移到基体表面，而在基体内部留下了大量孔洞，恶化了基体性能。通过适当的工艺措施，减少Ｂ２Ｏ３杂质的形成。
The influences of oxygen on the Mo 2FeB 2 ceramet have been studied. The results indicated that the combination of oxygen in the matrix with boron is able to form glass like B 2O 3 impurities apparently, which can move up to the upper surface of the matrix from interior of matrixand results in the porous structure in matrix, makes the mechanical properties of Mo 2FeB 2 ceramet bad heavily; taking proper technological measures, B 2O 3 impurities can be decreased.
