摘要
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。
Active screen plasma nitrocarburizing experiments of 3Cr13 stainless steel were carried out at different temperatures. The microstrueture and composition of the nitroearburized layer were characterized through microscopy and XRD. The microhardness and sliding wear behaviors were determined with microhardness testing, ball-on-disc wear tester and SEM. The results show that with the nitrocarburzing temperature increasing, the surface phases gradually precipitate CrN, α and e from the prime α＇N, γ＇ and e, and the surface hardness improves. The wear rate of nitrocarburized samples decreases by one order compared with untreated sample, and the wear resistance rises.
