摘要: 考察了氧對(duì)Mo₂FeB₂金屬陶瓷性能的影響。結(jié)果表明：基體中的氧能與硼形成表觀像玻璃的B₂O₃雜質(zhì)，燒結(jié)時(shí)這些B₂O₃雜質(zhì)能從基體內(nèi)遷移到基體表面，而在基體內(nèi)部留下了大量孔洞，惡化了基體性能。通過適當(dāng)?shù)墓に嚧胧瑴p少B₂O₃雜質(zhì)的形成，可制得較好綜合性能的Mo₂FeB₂金屬陶瓷。

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
