Abstract
Numerical methods were used to derive an improved estimate of the slope of the polarization curve in the vicinity of the corrosion potential. The resulting three-point linear polarization equation has the same form as the conventional two-point equation, but yields a substantially more accurate value for the corrosion current. For /a0/ = 10 mv and tafel constants (b1a and b2c) 30 mv or larger, the error in computing the corrosion current from the three-point equation is only 10 pct or less.
