Abstract
With two independent techniques (measuring the polarization resistance R(p) and weighing the specimens), B coefficients relating R(p) to the corrosion rate of the steels 20, 10XCH Pi, and 30XTCA, copper, and ma gnesium in nonstirred tap water are determined. The surface films form ed during corrosion have ohmic resistance that can be included in the R(p) measured by an R5126 indicator. This leads to anomalously high or anomalously low B values.
