摘要: 研究了涂有 K_2SO_4～Na_2SO_4 盐膜的工业纯铁在 O_2～0.1、0.5和1.0%(SO_2+SO_3)气氛中于560～750℃温度范围内的低温热腐蚀行为。结果表明,工业纯铁的低温热腐蚀是由低熔点的 K-Na-Fe 三元复合硫酸盐引起的,并依铁的溶解-铁的氧化物的沉积机制发展。

Abstract：Low temperature hot corrosion behavior of commercial pure iron coated with K_2 SO_4-Na_2 SO_4 was studied in O_2-0.1,0.5 and 1.0%(SO_2+ SO_3)gas environments in the temperature range of 560 to 750℃.The experimental results indicate that the low temperature hot corrosion of iron is caused by the formation of low melting ternary sulfate containing K,Na and Fe,and that the corrosion can be explained on the basis of dissolution-precipitation mechanism.
