摘要: 用浸泡腐蚀试验、电化学测试及表面分析技术研究了合金元素氮对双相不锈钢抗孔蚀性能的作用。试验结果表明加入氮使孔蚀电位升高并有利于奥氏体中含有更多的cr、Mo及Si,因而改善了双相成份分布。氮增强了Cr及Mo在钝化膜中.特别是在奥氏体上的形成的钝化膜中的富集,从而提高了膜的稳定性。
Abstract:The effect of nitrogen on the pitting resistance of duplex stainless steel was studied with immersion test, electrochemical measurements and surface analysis techniques. The results indicated that the addition of nitrogen into the duplex steel shifts its pitting potential towards more positive direction, favours austenite with higher contents of Cr, Mo and Si, and hence improves the composition partition in the duplex. Nitrogen enhances the enrichment of Cr and Mo in the passive film, especially for the film formed on austenite, so that the stability of passive film is increased.
