B. Electrochemical Potentials and Corrosion Mechanism For a certain range of composition, the intergranular constitutents of Nd-Dy-Fe-Co-Cu-Al-Ga-B magnets are only. The most widespread form of corrosion that is observed, uniform corrosion is characterized by corrosive attack proceeding evenly over the entire surface area, or a large fraction of the area of the metal under attack..
In chemistry, an electrochemical reaction mechanism is the step by step sequence of elementary steps, involving at least one outer sphere electron transfer, by which an overall chemical change occurs. Galvanic corrosion is either a chemical or an electrochemical corrosion . The latter is due to a potential difference between two different metals connected through a circuit for current flow to occur from the more active metal (more negative potential) to the more noble metal (more positive potential). Galvanic coupling is a galvanic cell in which the anode is the less corrosion- resistant
A home-made micro-electrode technique was used to investigate electrochemical corrosion of steel under a chloride-containing water drop, simulating the corrosion scenario encountered in pipelines The corrosion behavior of mild steel was first investigated in environments with and without H 2 S at pH 4.0 and 120 C, showing that magnetite is the dominant corrosion product layer in the initial stage of corrosion, due to a much higher saturation value than iron sulfide (mackinawite).

Mechanisms of uniform corrosion deposits corrosion under J. L. CROLET Elf-Aquitaine, 64018 Pau Cedex, France These mechanisms determine either the maintenance of bare metal or the precipitation of solid corrosion products, the build-up of a corrosion deposit and the control of its thickness, and finally, the kinetics of the electrochemical reactions under the deposit. Although it is …. Since electrochemical reactions are responsible for corrosion damage, electrochemical techniques should be capable of revealing the corrosion mechanism and evaluating the corrosion performance of anodized Mg alloys..
Abstract The aim of this work was to study the activation mechanism of pure aluminum in the absence and presence of indium ions in a chloride-containing medium using the electrochemical noise technique. A correlation was obtained between the noise response and the type of corrosion morphology observed by scanning electron microscopy (SEM).

In this paper, the corrosion mechanism of SSiC in acidic and alkaline environments is investigated by electrochemical methods. The changes of the microstructures during corrosion experiments are investigated by SEM and correlated with the mechanisms.
