WebAug 6, 2024 · The erosion-corrosion performance of X65 carbon steel at different flow conditions was electrochemically studied. Results show that the anodic polarization branch would have a significant distortion in the flowing electrolytes, leading to an overestimation of the Stern-Geary coefficient using the traditional Tafel extrapolation. It is found that the … WebJan 1, 2004 · The effect of Stern-Geary constant and the choice of electrochemical technique used to measure the corrosion rate are also discussed. ECR probe corrosion …

WebJun 1, 2010 · Geary's-C is a very nice and interpretable statistic. It ranges 0-1 and is, in essence, a global semivariogram. Geary's-C is not as sensitive to the specification of the neighbor matrix and as such can be a much more stable statistic than Moran's-I. However, it does not indicate diffusion/repulsion process if present in the data.
WebNov 18, 2024 · The Stern-Geary coefficient is related to the anodic, b a, and cathodic, b c, Tafel slopes as per Eq 3. The units of the Tafel slopes are V.
