Hydrodynamic Effects on Corrosion and Passivation of Copper in Borate Buffer Solution

The corrosion and passivation of copper was investigated with the copper rotating disk electrode(Cu-RDE) in borate buffer solution. It has been observed with the mixed potential theory that the corrosion potential for the rotation rate increase under the convective diffusion condition was increased. It was suggested that the chemical intermediates and product 13. the copper oxidation were .

Inhibition Effect of Amino Acids on the Corrosion of Aluminum in Artificial Sea Water

Inhibition effects of alanine and methionine on the corrosion of aluminum were investigated in artificial sea water. Based on the low coverage of alanine and methionine we suggested that alanine and methionine adsorption process in aluminum surface is Langmuir isotherm and the carboxyl ion of amino acids seems to be adsorbed on Al.
