Electrochemical methods are currently used to characterize the corrosion properties of metals. However, because of the easy use of these methods, the interpretation of the results could be sometimes difficult or wrong in terms of the metal corrosivit

We report an investigation of the pitting corrosion susceptibility of Zircaloy-4 alloy in presence of radiolytic chloride, nitrate and hydrogen peroxide. The electrochemical behavior of Zircaloy-4 was essentially studied using cyclic voltammetry and

A finite element numerical model was set up to calculate the secondary distribution of potential and current density at the surface of a buried tank. The steel gas tank of interest was protected by both coating and two sacrificial anodes (magnesium a
