Abstract

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.

Key words： cathodic protection; mechanism; challenge; buried steel pipeline
