摘　　要：利用X射线光电子能谱(XPS)研究了服役80 a以上SS400角钢表面氧化物的电子结构和价带结构。SS400角钢氧化膜的XPS实验结果表明,随着Ar+溅射时间持续2100 s,氧化膜中Zn^(2+)2p3/2和Fe^(3+)2p3/2的结合能分别为(1022.10±0.08)和(710.72±0.09)e V,基本保持不变,氧化膜中Fe、Cr和Mn原子分数都低于10%。氧化膜主要成分为Zn的氧化物和碳氧化合物。结合SS400角钢的化学成分和氧化膜的XPS结果,分析了SS400角钢耐腐蚀的原因。SS400 angle steel has served for more than 80 a in the high-voltage transmission tower in Liaoning power network. It did not suffer from evident uniform-and localized-corrosion, which indicates its good anti-corrosion resistance. In this work, the electronic structures and valence bands of main elements of the oxide scale formed on SS400 angle steel were characterized by X-ray photoelectron spectroscopy（XPS）. The results demonstrate that the binding energies of Zn2 ＋2p3/2 and Fe3＋ 2p3/2 were（1022.10±0.08） and（710.72±0.09） e V respectively as a constant binding energy during the Ar＋sputtering,the atomic percentages of Fe, Cr and Mn were less than 10%. The main components of the oxide scale on SS400 angle steel were Zn oxide and C-O chemical compounds. The reasons for good anti-corrosion resistance of the SS400 angle steel were analyzed with the XPS results of its oxide scale and its chemical composition.
