Abstract

A testing platform for studying the corrosion characteristics of grounding electrode materials was established in response to the corrosion phenomenon of pure copper grounding electrodes caused by DC interference current. Firstly, the variation law of grounding potential and corrosion behavior of copper grounding materials in typical soil of Shenyang were studied. Secondly, SEM, EDS, XRD and other techniques were used to observe the surface morphology of the corroded sample, analyze the composition of the corrosion products, and finally, a linear correlation fitting was performed between the corrosion rate calculated using interference current and the grounding potential. The results showed that there was a linear relationship between the initial and stable potential offsets and the corrosion rate measured using the weight loss method. The experimental results can provide a certain reference basis for engineering practice.
