文摘 研究了纯Cr、低合金钢及HP型耐热钢在450℃纯氧气氛中分别于在ZnCl2及KCl-ZnCl2盐膜下的腐蚀,结果表明,材料在混合盐膜下比在单一ZnCl2盐膜下发生了更严重的腐蚀,与低合金钢相比,纯Cr和耐热合金中的腐蚀产物更为疏松并易剥落,此外,HP耐热合金中还沿富Cr碳化物发生了晶闸侵蚀,从热力学角度讨论了形成Cr2O3型型保护膜的材料在含氯环境中的脱化机理。
其他语种文摘 The corrosion behavior of pure Cr, one low alloy steel and an HP-type heat-resistant steel were studied in the presence of ZnCl_2 and KCl-ZnCl_2 deposits respectively in oxidizing gaseous environments at 450 ℃. All materials suffered from seriously accelerated corrosion beneath mixture salts than in single ZnCl_2 deposit. The oxide scales formed on pure Cr and heat-resistant steel were easily to spall and had even worse adherence to the matrix compared with that on low alloy steel, whereas the latter had a higher mass gain during corrosion. Furthermore, Cr-rich Cr_7C_3 carbides were attacked preferentially induced by chlorine in comparison to the matrix of the heat resistant steel. The results show that the Cr-containing alloys do not exhibit excellent corrosion resistance to this chlorine-contaminant environment due to the poor adherence of the scales to the matrix. The accelerated corrosion mechanism for those Cr_2O_3-forming materials is discussed thermodynamically.
