[目的]研究0Cr16Ni5Mo1不锈钢在海洋大气环境-热腐蚀耦合作用下的耐腐蚀行为，为其应用提供数据支撑。[方法]通过自然大气环境暴露+热腐蚀试验和模拟加速腐蚀试验(包括湿热环境、酸性盐雾腐蚀和420℃涂盐热腐蚀)研究了0Cr16Ni5Mo1不锈钢在海洋大气环境-热腐蚀耦合作用下的腐蚀行为。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)及能谱仪(EDS)对样品进行相结构分析、腐蚀形貌观察及元素成分检测。[结果]经不同地区大气环境暴露1年及420℃涂盐热腐蚀150 h后，0Cr16Ni5Mo1不锈钢发生不同程度的腐蚀。随模拟加速腐蚀试验循环周期增加，0Cr16Ni5Mo1不锈钢的腐蚀速率增大，腐蚀程度逐渐加重。[结论]Cr16Ni5Mo1不锈钢表面自然氧化膜的耐腐蚀作用有限，因此将其应用于海洋大气环境-热腐蚀耦合场合时应进行适当的表面防护处理。
Abstract：[Objective] The corrosion behavior of 0Cr16Ni5Mo1 stainless steel under the coupling of marine atmospheric environment and thermal corrosion needs to be studied to provide data support for its application. [Method] The corrosion behavior of 0Cr16Ni5Mo1 stainless steel under the coupling of marine atmospheric environment and thermal corrosion was studied through natural atmospheric exposure followed by thermal corrosion test and artificial accelerated corrosion test(including damp heat environment, acidic salt spray corrosion, and 420 ℃ salt-coated thermal corrosion). The phase structure, corrosion morphology, and elemental composition of different specimens were analyzed by X-ray diffraction(XRD), scanning electron microscopy(SEM), and energy-dispersive spectroscopy(EDS). [Result] After exposure to different regional atmospheric environments for 1 year and 420 ℃ salt-coated thermal corrosion for 150 hours,0Cr16Ni5Mo1 stainless steel suffered corrosion to varying degrees. With the increasing of artificial accelerated corrosion cycle, the corrosion rate of 0Cr16Ni5Mo1 stainless steel was increased and its corrosion degree was gradually worsened.[Conclusion] The corrosion resistance of the natural oxide film on 0Cr16Ni5Mo1 stainless steel surface is limited. So it should be treated with appropriate surface protection when applied to the occasion coupled with marine atmospheric environment and thermal corrosion.
