| 摘 要： | 利用x射线衍射仪、电子探针研究了低温固体渗硼的渗层形貌、相组成和元素再分布特征。结果表明,低温固体渗硼的硼化层是由FeB,Fe_2B,Fe_3(C,B),Fe_3(Si,B)等相组成;硼化层的前沿无过渡区,FeB和Fe_2B生长过程中排挤出来的碳和硅没有发生远程扩散,而是就近形成Fe_3(C,B)和Fe_3(Si,B)等形式的含碳和硅的硼化物。

| Abstract: | By x-ray diffractometer, metallograph and EMP, studies morphology, composed phases and some elements redistribution of the low temperature bornized layer. Result shows: the layer consists of such phases as FeB, Fe_3B, Fe_3 (C, B)and Fe_3(Si,B),and no trasitional zone exists beyond the layer. Carbon and sillicon atoms repelled by the FeB and Fe_2B growth couldn't diffuse a distance, andso they nearby formed Fe_3(C, B) and Fe_3(Si, B) in the bornized layer. |
