在液态铅铋温度 350℃，流速控制在 0.5 m/s，饱和氧浓度（3.48×10^-6wt.%）试验条件下，T91、15-15Ti、316L 三种样品动态腐蚀 2000 小时后，利用扫描电子显微镜（Scanning Electron Microscope，SEM）、能谱仪（Energy Dispersive Spectrometer，EDS）、X 射线衍射仪（X-ray diffraction，XRD）分析仪器对腐蚀样品进行观察分析得出的结论如下：

（1）T91 表面形成三层结构氧化膜，从外到内依次是 Fe₃O₄（磁铁矿）、Fe-Cr尖晶石和氧元素急剧下降的内氧化层，总的氧化膜厚度约为 4.2μm；氧化膜能够有效减缓液态铅铋对基体材料的腐蚀。

（2）15-15Ti 表面形成一层较薄但是致密的氧化膜，厚度约为 1.2 μm。

（3）316L表面形成一层较薄Fe-Cr尖晶石氧化膜，厚度约为 1.3 μm。

The temperature of liquid lead bismuth is 350 ℃, the flow rate is controlled at 0.5 m/s, and the saturated oxygen concentration is 3.48 × 10^-6wt.%. Under the test conditions, after the dynamic corrosion of T91, 15-15Ti and 316L for 2000 hours, the corrosion samples were observed and analyzed by scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and X-ray diffraction (XRD). The conclusions are as follows:

(1) Three-layer structure oxide film is formed on the surface of T91. From the outside to the inside, Fe₃O₄ (magnetite), Fe-Cr spinel and the internal oxide layer with sharp drop of oxygen elements are successively formed. The total thickness of the oxide film is about 4.2 μm； The oxide film can effectively slow down the corrosion of liquid lead bismuth to the matrix material.

(2) A thin but dense oxide film is formed on the surface of 15-15Ti, with a thickness of about 1.2 μm.

(3) A thin Fe-Cr spinel oxide film is formed on the surface of 316L, with a thickness of about 1.3 μm.
