摘要：

The evolution of open-circuit potential, soluble copper concentration and impedance during immersion of Cu in deoxygenated neutral borate buffer containing 0.01-1.0 mol l(-1) NaCl was monitored for up to 3000 h. The open-circuit potential was found to be close to the CuCl2-/Cu equilibrium potential. No corrosion layer was detected by voltammetric scans and the soluble copper concentration reached a steady state. Experimental data were quantitatively interpreted by a kinetic model featuring CuOH and CuCl intermediates. The process through which the system reached steady state is tentatively related to a reaction that could lead to hydrogen evolution. (C) 2013 Elsevier Ltd. All rights reserved.
