Abstract/Summary Our recently developed plug-in specimens allow direct comparison between corrosion rates measured by weight loss, hydrogen evolution and from Tafel extrapolation of polarization curves. These have allowed identification of some of the reasons why Tafel extrapolation has previously not provided a good measure of steady state corrosion for Mg, because: (i) of crevice corrosion in the specimen mount, (ii) of decoupling of the Mg corrosion from the electrochemical measurements; and (iii) Tafel extrapolation has often been used to study Mg corrosion soon after specimen insertion into the solution, despite the fact that Mg alloy corrosion is often non-linear, the corrosion rate accelerates to a steady state rate after an initial period of low corrosion rate.
