埋地钢质管道阴极保护的研究进展

Research Progress on Cathodic Protection of Buried Steel Pipelines

阐述了均相金属腐蚀电极和复相金属电极的阴极保护机制的研究历程,介绍了复相金属电极阴极保护技术在实际工程应用中面临的挑战:极化电位的准确测量和阴极保护有效性准则的选取建立;阴极保护理论模型迄今未得到科学系统地阐述,在一定程度上限制了其工程应用。

In this paper,the research history of the cathodic protection mechanism of homogeneous metal corrosion electrodes and complex metal electrodes was summarized,and the challenges faced by complex metal electrode cathodic protection technology in practical engineering applications were introduced:the accurate measurement of polarization potential and the selection and establishment of validity criteria for cathodic protection;the theoretic model of cathodic protection has not been defined scientifically and systematically so far,which limits its engineering application to a certain extent.
