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，可制得较好综合性能的Mo₂FeB₂金属陶瓷。

Abstract:The influences of oxygen on the Mo₂FeB₂ ceramet have been studied. The results indicated that the combination of oxygen in the matrix with boron is able to form glass like B₂O₃ impurities apparently, which can move up to the upper surface of the matrix from interior of matrix and results in the porous structure in matrix, makes the mechanical properties of Mo₂FeB₂ ceramet bad heavily; taking proper technological measures, B₂O₃ impurities can be decreased.

Key words: Mo₂FeB₂ceramet oxygen
