Abstract

In 1949 a study was initiated by H. O. Teeple sponsored by Subcommittee VIII on Galvanic and Electrolytic Corrosion of the American Society for Testing and Materials (ASTM) Committee B-3 on Corrosion of Nonferrous Metals and Alloys. This study covered the atmospheric galvanic corrosion of magnesium coupled to a number of dissimilar metals and alloys. Previously, results were reported for two and one half years exposure at State College and Kure Beach. This report, sponsored by Subcommittee VII on Galvanic Corrosion of ASTM Committee G-1 on Corrosion of Metals, presents the final data from this study after an approximate 22-year exposure at these test sites.
