“…The anodic dissolution of Mg has been studied extensively (3)(4)(5)(6)(7)(8). The outstanding experimental facts of the dissolution which, as yet, are not satisfactorily explained are: (a) the anodic current efficiency in aqueous solutions is less than 100% (the anodic current efficiency is defined as the ratio of the actual coulombs passed to the theoretical coulombs obtainable from the actual weight loss assuming a magnesium valency of two); (b) the amount of hydrogen produced in the absence of added oxidizing agents is equivalent to the excess Mg dissolved at the anode; and (c) the corrosion film formed on Mg is composed of Mg, MgO, and Mg(OH)~ (9)(10)(11)(12)(13).…”

“…The electrochemical formation of monovalent Mg (3,4,5,8,14) has been postulated by various workers to account for the low current efficiencies; solution reactions of Mg + were postulated to account for the hydrogen and corrosion product formation. Robinson (6) has suggested that the low current efficiencies may be due to an enhanced corrosion rate at the anode since in an unbuffered solution the acidity at the metal-solution interface is higher than in the bulk of the solution for anodically polarized Mg.…”

The effect of current density, pH, and temperature on the anodic behavior, cathodic behavior, and corrosion of magnesium in aqueous solutions has been studied. A tentative mechanism for the anodic oxidation of magnesium is postulated. Local corrosion and/or undermining of metallic magnesium at the anode are appreciable and may, in fact, account for the observed low anodic current efficiencies of magnesium. An intergranular type of corrosion occurs at cathodically polarized magnesium at elevated temperatures. A hydrogen embrittlement theory is proposed to explain intergranular cathodic corrosion. ) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.
