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).

Book Description
Pitting corrosion of molybdenum-ion-implanted, depleted uranium -0 75 Ti (DU -0 75 Ti) has been studied electrochemically in acidic. neutral, and alkaline solutions containing sodium chloride, and the results have been compared to those of the unimplanted DU -0 75 Ti. The data show that Mo implantation shifts the pitting potential of DU -0 75 Ti in the noble direction in acidic and alkaline solutions In neutral 50 ppm Cl- solution, however, there is no beneficial effect of Mo implantation Auger analysis studies show that before exposure to the solutions, all the molybdenum is in the oxide, which is approximately l000 A thick After electrochemical scans in the acidic and alkaline chloride solutions, most of the Mo disappears from the oxide However, no decrease in Mo concentration is found after exposure in neutral chloride solution It is proposed that the implanted molybdenum dissolves in the acidic and alkaline solutions and forms simple or complex molybdates that inhibit pitting corrosion. The implanted molybdenum does not dissolve in the neutral chloride solution and inhibition does not occur.

The High Temperature Aqueous Corrosion of Uranium Alloys Containing Minor Amounts of Niobium and Zirconium

Book Description
Alloys of uranium with niobium show good corrosion resistance in degassed, distilled water to about 315 degrees C. The alloys must be quenched from the gamma phase in order to have high temperature corrosion resistance. The corrosion resistance is destroyed by over-aging at temperatures as low as 350 degrees C. Of those tried, the alloy with best resistance to thermal aging is the uranium-5% zirconium-1.5% niobium alloy. At 290 degrees C, optimum heat treatment can result in a rate of corrosion of about 6 mg/cm sq/day. Certain moderate aging treatments, e.g., 400 degree C for two hours, result in improved corrosion resistance in the initial stages of corrosion. Alloys containing 3% niobium and small amounts of tin show promise. In addition to aging, the alloys are also sensitive to hydrogen content. Ultimate corrosion failure is believed due to absorption of corrosion product hydrodgen.
