Grounding grid is an important device guaranteeing the operation of the people, electrical equipments and power grid. However, the corrosion of grounding grid affects the security of the power grid system, what's worse, it makes huge economic losses and serious social impact. We found from the research that the copper-clad steel for grounding grids has any advantages to better economic gain and good corrosion resistance at the same time. In this paper, using electrochemical impedance spectroscopy (EIS), polarization curve measurement, scanning electron microscopy (SEM) and so on, the corrosion behavior of copper-clad steel for grounding grids in the coastal soil have been researched. The results indicated that an increase of the soil salinity decrease the corrosion resistance of copper-clad steel, and the latter stage is less than the mid-term stage. The resistance increase and then tend to be stable with the increase of immersion time. The corrosion resistance of copper-clad steel in the non-salinized and light salinized soil is better.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
