Electrochemical Polarization I . A Theoretical Analysis of the Shape of Polarization Curves
Milton Stern,A. L. Geary +1 more
TL;DR: In this paper, a linear dependence of potential on applied current is described for a corroding electrode by treating it in a manner analogous to that for a non-corroding electrode, and an equation is derived relating the slope of this linear region to the corrosion rate and Tafel slopes.
