Title: LITERATURE SURVEY OF THE CORROSION OF MAGNESIUM AND MAGNESIUM ALLOYS. Period covered July 1955 to November 1956

Abstract

Features mentioned as well established are: Corrosion of Mg, except in a dry atmosphere, is galvanic in nature; the purest Mg has the lowest corrosion rate; the effect of impurities is characterized by a critical concentration, the tolerance limit, below which there is little influence of the impurity; the naturally formed films are stable only under special, and very often limited conditions and are therefore not generally protective. However, under reasonable inland atmospheric conditions, and even in fresh water, the corrosion resistance of Mg and some of its alloys is quite satisfactory. Many artificial coatings have been developed that give additional protection. Summaries are included on general corrosion behavior of Mg, experiments with Mg single crystals, test procedures, effects of temperature and other parameters, structure of surface films, effect of impurities and additions, corrosion behavior of Mg alloys, interpretation of corrosion experiments, stress corrosion, galvanic coupling corrosion, and antificial protective films.
