研究了 12Cr铁素体钢在模拟煤燃烧过程氧化一硫化交变气氛中的腐蚀行为四循环腐蚀后生成由硫化物和氧化物交替组成的层状腐蚀膜,并发生了疏渗透入氧化膜而氧渗透入硫化膜的现象其腐蚀动力学依赖于气体化学成分的变化以及所形成的氧化、硫化膜的特性 The corrosion behavior of 12Cr ferritic steels in an oxidative-sulphided alternating atmosphere of simulating coal combustion was studied. After four cycles of corrosion, a layered corrosion film consisting of alternating sulphides and oxides was formed, and the infiltration into the oxide film took place Oxygen infiltration into the phenomenon of sulfide film corrosion kinetics depends on changes in gas chemical composition and the formation of the oxidation, the characteristics of the cured film
