The hardness gradient, depth, microstructure and phases of nitrided layers were measured with Microhardness Apparatus, Microcopy and X-ray diffractometer.
利用显微硬度计、金相显微镜和X射线衍射仪测定了渗氮层的硬度梯度、层深、显微组织和相组成。
2
The surface layers are characterized by means of the optical microscope, Xray diffraction, transmission electronic microscope, and micro hardness testing machine.
用X 射线衍射、光镜和透射电镜对表层变形层金相组织、晶粒尺寸、显微硬度进行分析。
3
The microstructure change and the mechanism of the change in hardness were studied by small-angle X-ray scattering.
