摘　　要：研究了离子注渗W和渗碳处理对低碳结构钢显微组织、表面性能的影响。结果表明,离子注渗后低碳结构钢的表面硬度显著提高。本文采用X射线衍射分析、扫描电镜和透射电镜等方法,对其显微结构进行研究,通过对其产生的弥散相进行分析,确定该弥散相为WC,从而引起材料表面强化。The effects of ion implanting W and carbonizing on the microstructure and surface performance of low carbon structural steel were investigated. The results show that the surface hardness improves after implanting. The microstructure of low carbon structural steel after ion implanting were studied using X-ray diffraction, scanning electron microscopy and transmission electron microscopy methods. By the new phase dispersion analysis, the new phase is WC, which leads to material surface hardening.
