摘要: 抗硫酸露点腐蚀钢的表面研究张瑗，纪元，朱逢吾，梁成广，肖纪美（北京科技大学北京１０００８３）１引言以高硫重油为燃料的锅炉烟气中常含有较多的ＳＯＺ、ＳＯ３，在锅炉的低温部位，如空气预热器、集尘器、烟道、烟囱等处引起所谓的“硫酸露点腐蚀”．日本开发的各种Ｓ－ＴＥＮ钢具有良好的抗硫酸露点腐蚀性能．在成分上，Ｓ－ＴＥＮ钢与普通碳钢不同的是：它含有少量的Ｃｌｌ、Ｓｂ元素．但这些合金元素提高抗硫酸露点腐?...

Abstract：S-TEN steel surface was investigated by auger electron spectroscopy (AES) and scanning electronmicroscopy (SEM). Elements S and Sb have segregated on the surface of the hot rolled S-TEN steel, andtheir contents are 4.24 at% and 0.50 at% respectively. The surface segregation of the elements S, Sb andCu has also been found after immersion of the sample in sulphuric acid. The segregation layer of sulphur isthicker than that of copper.The enrichment of Cu, S and Sb in surface layer is beneficial for the resistanceof the S-TEN steel to sulphuric acid dewpoint corrosion.
