Abstract

Copper, works as a protector of used fuel rods of nuclear power plant, can suffer most corrosion for its properties. While the copper, once reacting with sulfate/sulfide solutions from oil when buried deeply, may involve new corrosion problem. In this paper, mass loss experiments and potentiodynamic polarization are employed to investigate the corrosion behavior of copper in sulfide/sulfate solutions. The results of the mass loss indicated that when the temperature is 60°C, the corrosion rates of copper decrease with the increase of concentration of Na2S and Na2SO3. The potentiodynamic polarization of copper indicated that under the same temperature, the corrosion current densities of pure copper in Na2S, NaCl and Na2SO4 aqueous solutions increased with the increase of solute concentrations. Keeping the concentration of each solution constant, the corrosion rate increases quickly with the rise of temperature. It should be highlighted that copper corrodes very fast in the Na2S solution among these solutions.
