摘要/Abstract

摘要： 采用离子渗氮工艺对一种Fe-C-Cr-Ni-Mn-V沉淀硬化型奥氏体不锈钢进行表面改性处理。利用光学显微镜(OM)、X射线衍射(XRD)、电子探针显微分析仪(EPMA)和维氏硬度计对不同离子渗氮温度下渗层的组织和性能进行了研究。结果表明,Fe-C-Cr-Ni-Mn-V沉淀硬化型奥氏体不锈钢经430~520 ℃离子渗氮处理10 h后,试样表面均形成一层厚度均匀的渗氮层,表面硬度显著增大。随着离子渗氮温度的升高,渗层厚度增大,520 ℃渗氮时渗层厚度达到78 μm。当渗氮温度为430 ℃时,渗层表面主要由γ_N+CrN+γ′-Fe₄N相组成;当渗氮温度升高至520 ℃时,渗层表面主要由γ′-Fe₄N+CrN+ε-Fe_2-3N相组成。在3种渗氮温度下,渗层中均有CrN析出,导致渗层耐蚀性低于基体组织。

Abstract: The surface of a Fe-C-Cr-Ni-Mn-V precipitation-hardened austenitic stainless steel was modified by plasma nitriding. Microstructure and properties of the nitrided layer at different nitriding temperatures were investigated by means of optical microscope (OM),X-ray diffraction (XRD), electron probe microanalysis (EPMA) and Vickers hardness tester. The results show that nitrided layer with uniform thickness on the specimen surface is formed by plasma nitriding at temperatures ranging from 430 ℃ to 520 ℃ for 10 h, and the surface hardness is significantly improved. The thickness of the nitrided layer increases with the increase of nitriding temperature and reaches 78 μm at 520 ℃. The infiltration layer is composed of γ_N, CrN and γ′-Fe₄N phases after nitriding at 430 ℃, and composed of γ′-Fe₄N, CrN and ε-Fe_2-3N phases when the nitriding temperature increases to 520 ℃. Precipitation of CrN is found in the infiltration layer at all the three nitriding temperatures, resulting in the poor corrosion resistance compared with that of the substrate.
