摘要
2205 双相不锈钢（2205DSS）在阳极电位下于 420 °C 的氨气环境中进行等离子氮化。采用 X 射线衍射 (XRD) 和扫描电子显微镜 (SEM) 对氮化层进行了表征。通过电化学极化测试和针盘磨损实验评估了氮化层对 2205DSS 的耐腐蚀性和耐磨性的影响。结果表明，基体上形成了氮膨胀奥氏体，氮化 4 小时和 10 小时的样品上形成的氮化层增强了 2205DSS 的耐腐蚀性和耐磨性。
Formation and properties of nitrided layer on 2205 duplex stainless steel by anodic plasma-nitriding assisted with hollow cathode discharge
2205 duplex stainless steel (2205DSS) was nitrided at 420 °C by plasma nitriding in an ammonia atmosphere under anodic potential. The nitrided layer was characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The impact of the nitrided layer on the corrosion and wear resistance of 2205DSS was evaluated through electrochemical polarization tests and pin-on-disc wear experiments. The results revealed that nitrogen-expanded austenite was formed on the substrate, and the nitrided layer developed on the samples nitrided for 4 and 10 h enhanced both the corrosion and wear resistance of 2205DSS.
