摘要
文章介绍了用不同剂量的氮离子束和氩离子束分别轰击纯铁镀铬样品，研究其在１ＮＨ＿２ＳＯ＿４水溶液中的电化学腐蚀行为。结果表明：不同剂量的氮离子束混合样品具有相当好的耐蚀性能；低剂量的氩离子束混合样品也在一定程度上提高了纯铁的耐蚀性能，但高剂量的氩离子束混合却降低了纯铁的耐蚀性能。ｘ光衍射仪的分析，解释了实验结果。
In this paper,the electrochemical corrosion behaviours of the N￣(+) ion beam mixing and Ar￣(+)ion beam mixing on Cr─coated iron samples in 1 N H_2SO_4 solution have been studied.The anodicpolarization test shows that N￣(+) ion beam mixing treatment can increase corrosion resistance ofiron remarkably.But the Ar￣(+) ion beam mixing treatment does not have such an effect when it isin a large dose,These results are well explained by the X─ray diffraction analysis.
