研究了500 ~ 700℃NaCl沉积和水蒸气存在下1Cr-11Ni-2W-2Mo-V钢的腐蚀行为。结果表明，没有NaCl沉积时腐蚀不明显，而在任何温度下NaCl和水蒸气同时存在时，腐蚀都明显加速。采用光学显微镜（OM）、x射线衍射（XRD）、扫描电镜（SEM）和电子探针微分析（EPMA）对腐蚀产物进行了分析。提出了水蒸气和NaCl协同作用对钢腐蚀的机理。
The corrosion behavior of 1Cr-11Ni-2W-2Mo-V steel was studied in the presence of a NaCl deposit and water vapor at 500-700 degrees C. Results indicated that corrosion was not obvious without an NaCl deposit, while corrosion was accelerated remarkably by the simultaneous presence of NaCl and water vapor at any temperature. Optical microscopy (OM), X-ray diffraction (XRD), scanning electron microscopy (SEM), and electron-probe microanalysis (EPMA) were used to analyze the corrosion products. A mechanism of the synergistic effect of water vapor and NaCl on corrosion of the steel is proposed.
