Corrosion behavior of buried pipeline in presence of AC stray current in a controlled environment (Paper no. C2015-5588)

May 29, 2015 by Mariano Iannuzzi

This blog entry provides the link to download our final NACE CORROSION 2015 publication on corrosion of carbon steel in the presence of alternate currents (AC). Elmira Ghanbari presents a model, based on fundamental corrosion principles, which estimates the effect of an applied AC interference on Faradaic processes leading to corrosion.
