摘要
开发了一种可同时监测磨损速率与腐蚀速率的新型电阻-电化学探针,并利用模拟管道工作环境的循环管路分别在静态腐蚀环境与磨损腐蚀环境中测试了该探针的工作性能。结果表明:电阻-电化学探针可以探测到磨损腐蚀的发生,并能够实现对磨损速率与腐蚀速率的监测;在测试过程中,磨损速率随着腐蚀速率下降而下降,电阻-电化学探针很好地监测到了磨损过程的动态变化。
A novel electrical resistance-electrochemistry(ER-EC)sensor was developed,which can monitor erosion rate and corrosion rate simultaneously.The working performance of the ER-EC sensor was tested under static corrosion condition and erosion-corrosion condition using a flow loop simulating the working condition of pipeline.The results show that the ER-EC sensor can detect the occurrence of erosion-corrosion,and can realize the monitoring of erosion rate and corrosion rate.The erosion rate descended with the decrease of corrosion rate,indicating that the dynamic vibration of the erosion can be well captured through the ER-EC sensor.
