The Bureau of Mines has conducted research on the preparation and subsequent fabrication of iron and titanium-based intermetallics as part of its effort to develop alternate materials for use in the mining and minerals processing industries. Part of the research involved a study of the corrosion behavior of several of these materials in aggressive environments. Tests were conducted to determine the effects of composition, solution aeration, and exposure time on the corrosion rates of the intermetallic materials. Titanium had the lowest corrosion rate of all the metals tested. Of the intermetallics tested ti3al had the lowest corrosion rate, tial has the second lowest corrosion rate, and feal had the highest corrosion rate.
