✦ Synopsis
The non-Faradaic material loss is the difference between the material loss measured by the weight loss method and the one determined by Faraday's secondary law. Being observable in flowing corrosive electrolytes, it is promoted by increasing wall shear stress and anodic dissolution, is reduced by the increasing strength of electrode, and disappears in quiescent electrolytes or under cathodic protection. Therefore, the non-Faradaic material loss is likely a result of certain corrosion-aided mechanical damage mechanisms. A phenomenological model is proposed for the quantitative evaluation of the non-Faradaic material loss. The applicability of this model has been verified by the test data measured in both aqueous and non-aqueous electrolytes.
