    Abstract

    This paper reports on the progress of investigations being conducted at Panama Canal Zone, relative to corrosion of dissimilar metal couples exposed in the atmosphere, in the soil, and in seawater. Machined specimens of aluminum, brass, magnesium, Monel, steel, stainless steel, and titanium alloys are included in this study.

    Exposure of dissimilar and similar (control) metal couples was initiated over 2 years ago for a planned maximum 5-year exposure. Couple replicates (four of each metal) are removed from exposure periodically and returned to the laboratory for visual examination and weight loss determinations to evaluate the corrosion effects of each of the environments on the various couples. A total of seven removals from each environmental exposure is planned during the course of the corrosion investigations. To date, five removals of atmospheric specimens, five removals of seawater immersion specimens, and four removals of soil burial specimens, have been completed over a 2-year period and evaluated by this laboratory. Results of findings to date are presented in this paper.
