The corrosion of copper in aqueous solutions containing ≥5×10−4mol/L sulphide and the ensuing accumulation of corrosion product deposits (as chalcocite Cu2S) occurs non-uniformly indicating the occurrence of microgalvanic coupling between net anodic and net cathodic surface locations. A series of novel electrochemical experiments were designed to confirm the occurrence of this process and a series...
The corrosion of copper in aqueous sulphide environments is rapid and can occur under transport limited conditions. At sufficiently high sulphide flux, microgalvanic corrosion can be supported between areas of the surface covered by compact sulphide deposits and other areas covered only by a porous deposit. This leads to excessive crystal growth at the cathodes (compact film) and localized corrosion...
