Abstract A suit of electrochemical cell which was used to in vestigate the corrosion behavior of metals under different thin layer electrolyt e was designed.The Luggin probe of the cell was inserted backward of the working electrode.The results showed the layer thickness mainly affected the cathodic p rocess of Cu in the electrolyte (0.5 mol/L HCl+0.25 mol/L Na2SO4),the anodic dissolution changed from Tafel zone to limiting current zone.Moreover the corro sion potential increased with decreasing of the layer.

Key words: thin layer electrolyte Cu corrosion cell
