摘要:

通过实验室模拟垃圾焚烧炉中水冷壁环境，研究了新型奥氏体不锈钢254SMo、904L和317L在750、850和950 ℃下NaCl盐中的热腐蚀行为，获得了腐蚀动力学曲线；利用SEM/EDS和XRD对3种材料腐蚀产物的形貌和组成进行了观察和分析，探讨了热腐蚀机理。结果表明：3种不锈钢在热腐蚀过程中都表现为失重，并且随着温度升高和时间延长失重增加，按耐蚀性排序为254SMo不锈钢＞904L不锈钢＞317L不锈钢；Mo的添加可以降低材料在氯盐中受到的侵蚀；在850和950 ℃下3种奥氏体不锈钢还发生了严重的晶间腐蚀。热腐蚀机理为“活性氧化”，生成的氯气会参与反应并持续循环。

Abstract：

Waste incinerators are faced with many high-temperature corrosion problems because they work at high temperatures all year round. The NaCl induced hot corrosion behavior of three novel austenitic stainless steels 254SMo, 904L and 317L in NaCl salt at 750, 850 and 950 ℃ was studied in order to simulate the corrosion emerged on the fire side of tubes in waste incinerator by means of corrosion kinetic measurement, SEM/EDS and XRD. The results show that the three austenitic stainless steels show mass loss during the hot corrosion process, their corrosion resistance may be ranked as follows: 254SMo stainless steel ＞904L stainless steel ＞317L stainless steel, whilst their mass loss increases with the increase of temperature and time. The addition of Mo can alleviate the corrosion of the steels in the chloride salt. Serious intergranular corrosion occurred in the three austenitic stainless steels at 850 and 950 ℃. The hot corrosion reaction follows the so called “active oxidation” mechanism, and the generated chlorine gas will participate in the reaction cycle.

Key words： austenitic stainless steel hot corrosion corrosion kinetics chlorination
