XRD and EDS analysis indicate that at static condition, the composition of the scale is CO3, while the scale changes to CO3 at dynamic conditions. The increment in flow rate increased the thickness of the scale remarkably, but had little influence on the hardness and Young's modulus of the scale. The fracture toughness of the scale exhibited the lowest value at the flow rate of 0.5 m/s whereas the adhesion strength increased with increasing the flow rate.

结果表明，静态条件下形成的腐蚀产物膜的主要成分为CO3，动态条件下的主要成分为CO3；介质的流动能够促进腐蚀产物膜的形成，但对膜的硬度以及杨氏模量影响不大；腐蚀产物膜的断裂韧性随着流速的增大先下降后上升，流动状态下内层腐蚀产物膜的致密性较好，膜与基体的结合强度较高。
