摘要:

研究了500和600 ℃下N₂-0.26%HCl-1.6%O₂-3.2%CO₂混合气体中Q235钢的高温腐蚀行为。结果表明，在两个温度下Q235钢均出现了明显的腐蚀增重。随着温度的升高，腐蚀速率迅速增加。在两个温度下形成的氧化膜比较类似，分层明显，外层为较厚的Fe₂O₃层，内层为Fe₃O₄。大部分氧化膜表面出现了剥落和起皮，600 ℃下更为严重，而且在此温度下Fe₃O₄层中出现了大量孔洞。Q235钢的腐蚀符合“活化氧化机制”，在600 ℃温度下尤为明显，即挥发性的金属氯化物在金属与氧化膜界面处形成，向外挥发扩散，最终在氧压较高的区域生成金属氧化物。因此，在氧化性含Cl气氛中，Q235钢不适合在500 ℃以上的工况中使用。

Abstract：

The chlorine-induced corrosion behavior of Q235 steel in N₂-0.26%HCl-1.6%O₂-3.2%CO₂ mixed gas at 500 and 600 ℃ was investigated. At both temperatures, the Q235 steel presented obvious mass gain and the corrosion rate increased rapidly with the increase of temperature. The scales formed at both temperatures are very similar, with formation of an outer thicker Fe₂O₃ layer and an inner Fe₃O₄ layer. Most of the surface of scales peeled off and the case is more serious at 600 ℃. Furthermore, at this temperature a large number of holes appeared in the Fe₃O₄ layer. The corrosion mechanism of Q235 steel conforms to the “activated oxidation mechanism”, especially at 600 ℃, which means that volatile metal chlorides form at the metal/oxide interface and then diffuse outwards, turning into oxides finally in the region of higher oxygen partial pressure. Therefore, Q235 steel is not suitable to be used above 500 ℃ in an oxidizing chlorine-containing atmosphere.

Key words： Q235 steel chlorine-induced corrosion high temperature corrosion activated oxidation
