中文摘要：采用粉末包埋法在P110钢表面制备渗铬层；借助扫描电子显微镜、X射线衍射仪和显微硬度计，对渗铬层的显微组织、相组成和显微硬度进行了分析和表征，并通过无润滑条件下的球－盘式摩擦磨损试验研究了渗铬处理对其摩擦磨损性能的影响。

To the materials , there are rare dislocations in their crystal grains; to the unstrengthened samples, there are many dislocations which well-distributed in their grains; and to the strengthened samples, there are a large amount of dislocations scattered along their grain-boundaries, that is, the dislocations form a dislocation wall which is of great dislocation density.

又经透射电子显微镜对各种样品微观组织结构进行分析，发现其位错组态明显不同：①原材料样品中的晶粒内仅存在有非常稀疏的位错线；②未经过强化的样品中可观察到大量均匀分布的位错，分布密度相对较高；③在经过低载锻炼强化的样品中，可观察到大量的晶粒内在晶界附近聚集着一道密度很高的位错墙。
