摘 要:通过电化学测试方法对等离子氮化处理前后铁的耐腐蚀性进行研究.采用扫描电子显微镜(SEM)对极化试验后样品表面的腐蚀形貌进行观察.结果表明,等离子氮化处理后的样品的蚀孔数量少,其腐蚀程度明显优于未经处理的样品.应用X射线衍射(XRD)及X射线光电子能谱(XPS)分析其腐蚀机理.结果证实,等离子氮化处理后铁的耐腐蚀性能得以改善,归因于材料表面形成的铁氮及铁氧结合层.Electrochemical corrosion tests were performed to study the corrosion resistance of iron before and after plasma nitri- ding. The microstructures and pitting corrosion behavior of samples after polarization were investigated by scanning electron mi- croscope (SEM). The results showed that anti-corrosion performance of surface-modified specimen was obviously improved in so much as its number and extent of pitting decreased as compared with the untreated sample. According to the results of X-ray dif- fraction(XRD) and X-ray photoelectron spectroscopy( XPS), it is concluded that the improved corrosion behavior is ascribed to the new formed phases, of Ferrite nitride as well as Ferrite oxide near the surface, brought about by plasma nitriding.
