基于阵列电极技术使用自制的环路系统并采用极化、计算流体力学(CFD)模拟和表面分析技术研究环路系统中弯管段流速对 AZ91D 镁合金腐蚀行为的影响。实验结果表明，AZ91D 镁合金的腐蚀速率随着流速的增加而增加，且 AZ91D 镁合金在流动介质中的腐蚀可能存在临界流速。当介质的流速超过临界流速时，流体力学因素在 AZ91D 镁合金腐蚀中占主导地位；反之，电化学腐蚀因素占主导地位。
A loop system was used to investigate the effect of flow velocity on corrosion behavior of AZ91D magnesium alloy at an elbow of loop system based on array electrode technology by polarization, computational fluid dynamics (CFD) simulation and surface analysis. The experimental results showed that the corrosion rate increased with increasing flow velocity, and a critical flow velocity could exist in the corrosion of AZ91D magnesium alloy. When flow velocity exceeded the critical flow velocity, fluid hydrodynamics was dominant in the corrosion of AZ91D magnesium alloy. On the contrary, the electrochemical factors were dominant.
