摘要
本文采用铁基触媒加入硼铁的方法,在高温高压条件下合成了含硼金刚石。利用电子探针(EPMA),透射电子显微镜(TEM)两种检测手段,分析了含硼金刚石金属包膜的微观组织结构、化学组成成分、各组成成分的物相及其可能形成的原因。研究结果表明:金属包膜的成分及其物相由正交立方结构的(Fe,N i)3C、面心立方的γ-(Fe,N i)、面心立方的Fe23(C,B)6及少量的FeB、N i3B组成,这些成份主要来源于原材料,其含量在高温压过程中是瞬间变化的。
In this article, boron-doped diamond was synthesized at high temperature and high pressure （HTHP） by using boroniron alloy added Fe-based catalyst. Microstruetures and composition of the boron-doped diamond film were systematically investigated using electron probe microanalysis （EPMA） and transmission electron microscopy （TEM）. Some possible reasons of formation of the above were discussed. The results showed that the composition and microstructures consisted mainly of orthorhombic （Fe,Ni）3C, f. e. e. γ-（Fe,Ni） , f. e. e. Fe23 （C, B）6 and very. little FeB. They mainly come from the starting materials ,and their concentration is transiently variable.
