Study on Corrosion Behavior of Copper-Clad Steel Bars with Unclad Two-End Faces for Grounding Grids in the Coastal Soil

Abstract:

The corrosion behavior of copper-clad steel for grounding grids in the coastal soil have been investigated using electrochemical impedance spectroscopy (EIS), polarization curve measurement and scanning electron microscopy (SEM). The results show that the corrosion current density of copper-clad steel increase with the increase of soil salinity, 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 fine.
