本实验用Ｘｋ光电子能谱（ＸＰＳ）和俄歇电子能谱（ＡＥＳ）分别对碳钢材料在不同温度的亚硫酸铵制浆蒸煮液中的腐蚀产物进行了表面分析．发现在温度较高的条件下，碳钢处于钝化态时，其表面产物的外层为亚硫酸亚铁铵结晶层，内层为铁的氧化物．而在温度较低的条件下，碳钢处于活化态时，其表面产物的外层为硫化亚铁、铁的氧化物和亚硫酸亚铁铵的混合物，内层主要为硫化亚铁． In this experiment, the corrosion products of carbon steel in ammonium sulfite pulping cooking liquor with different temperature were analyzed by XPS and Auger electron spectroscopy (AES) respectively. It is found that under the condition of high temperature, when the carbon steel is in the passive state, the outer layer of the surface product is the ferrous ammonium sulfite crystal layer and the inner layer is the iron oxide. In the lower temperature conditions, when the carbon steel is in the activated state, the outer layer of the surface product is a mixture of ferrous sulfide, iron oxide and ammonium ferrous sulfite, and the inner layer is mainly ferrous sulfide.
