采用活性屏等离子氮碳共渗技术对3Cr13不锈钢在不同温度下进行处理,并采用光学显微镜和X射线衍射仪对渗层的组织形貌和成分进行分析,利用显微硬度计、球-盘摩擦磨损试验仪、扫描电镜研究了材料的硬度及摩擦磨损性能。结果表明,随处理温度升高,试样表层相组成由α’_N相+ε相+γ’相逐渐转变成α相+CrN相+ε相,试样表面显微硬度增加,磨损率降低约一个数量级,耐磨性能提高。
The reactive plasma nitrocarburizing was used to treat 3Cr13 stainless steel at different temperatures. The morphology and composition of the infiltrated layer were analyzed by optical microscope and X-ray diffractometer. The microhardness tester, ball-disk friction Wear tester, scanning electron microscopy study of the material hardness and friction and wear properties. The results show that as the processing temperature increases, the surface phase composition gradually changes from α’_N phase to ε phase to γ phase to α phase + CrN phase + ε phase. The microhardness increases and the wear rate decreases by about An order of magnitude, improved wear resistance.
