Abstract

"The increasing demand for magnesium and magnesium- base alloys in the manufacture of aircraft has stimulated a great amount of research into the corrosion characteristics of these materials. The result of such research has been the development of suitable magnesium alloys and protective coatings to retard corrosion.

The basic mechanism of the anodic dissolution of metals such as magnesium, zinc, and cadmium in salt solutions is not completely known. Several schools of investigators have proposed different and opposing theories to explain the discrepancies which often arise between coulometer data and the weight loss of metal electrodes in certain salt solutions.

The purpose of this investigation was to study the anion effect on the dissolution and disintegration of magnesium. If anion adsorption is important in these processes, then varying the ionic species present should alter kinetic parameters for the dissolution reaction and the apparent valence for the disintegration. To this end, the self-dissolution was studied in hydrochloric, hydrobromic, and hydriodic acids and the anodic dissolution in one normal solutions of potassium sulfate, potassium chloride, potassium nitrate, potassium bromide, and potassium iodide"--Introduction, page 1.
