Active-passive behavior was exhibited in sulfuric acid, sodium hydroxide, ammonium hydroxide, sodium sulfate, sodium nitrate, sodium chromate, and ammonium chromate solutions. Chloride additions as small as 0.005M destroyed passivity and caused pitting. Chromates, sulfates, and nitrates behaved as inhibitors in solutions containing low concentrations of chlorides. The uranium-molybdenum alloys were more resistant to corrosion in chloride solutions than the uranium-titanium alloys. Author
