| 摘 要： | 在一台普通的二圆X射线衍射仪上，利用不对称布拉格反射STD（试样相对于入射线倾斜在某一角度α0，进行2θ扫描）技术与常规CBD（正常的θ/2θ偶合扫描）模式相结合的方法，对铁钼粉末冶金抗磨材料的摩擦表层、次表面层及体相的物相纵向进行了较全面分析，特别揭示了摩擦次表面层Fe-C亚稳相的存在，对材料的摩擦性能有严重影响。

| Abstract: | The asymmetrical Bragg reflection STD(sample tilting diffraction) scan mode coupled with conventional X _ ray diffraction CBD(conventional Bragg diffraction) mode is used to determine phase composition of Fe-Mo powder metallurgy antiwear material with a conventional X _ ray diffractometer. The result showed that the subsurface layers below the Fe-Mo powder metallurgy material surface after friction appeared an Fe-C metastable phase. It affects seriously the properties of the Fe-Mo powder metallurgy antiwear material. |
