Stern geary equation
網頁The corrosion current density i corr of the zinc coating was estimated from the monitored R p using Stern–Geary equation. The corrosion mass loss Δ M , which was obtained from the i corr vs time curve, was plotted vs the wet–dry cycle number. 網頁Journal of The Electrochemical Society, Volume 104, Number 1 Citation M.

網頁2016年8月18日 · where B is the Stern-Geary coefficient, the inhibitor efficiency can also be expressed as: Clearly, if B is independent of the presence of the inhibitor it cancels out of Equation 3 . This is likely to be a reasonable assumption for cases where the type of corrosion behavior observed (i.e. active or passive) is independent of the presence of the … 網頁2013年7月12日 · For a spatial population, the critical value of Moran’s index is It = 0, and the threshold of Geary’s coefficient is Ct* = 1. These are indisputable. However, for a spatial sample, the consensus has not yet been reached so far. In many previous works, the threshold value of Moran’s index was regarded as It* = 1/ (1- n) [10].
