摘要: 在700～800℃的温度范围内,研究了工业纯铁和铁铬合金在有Na_2SO_4-MgSO_4-CaSO_4盐膜存在时在O_2-0.1.％(SO_2+SO_3)气氛中的腐蚀动力学和腐蚀产物的形貌。结果表明,三元硫酸盐加剧了纯铁和铁铬合金的腐蚀,这一加速作用远较在空气中的显著。以实验结果为依据,讨讨了腐蚀机理,认为加速作用是由硫化所致。

Abstract：The corrosion kinetics and corrosion product morphology of commercial pure iron and some Fe-Cr alloys were studied in O_2-0.1 %(SO_2 + SO_3) environment at 700～800℃ when there existed a thin layer of ternary sulfa tes, Na_2SO_4-MgSO_4-CaSO_4, on the surface of the alloys,The experimental results showed that the presence of sulfates induced hot corrosion of commercial pure iron and some Fe~-Cr alloys, and that hot corrosion in O_2-0.1%(SO_2+SO_3) was much more severe than that in air. On the basis of the experimental results, a sulfidation mechanism is proposed to explain this kind of hot corrosion.
