Abstract
Electrochemical behavior of an alloy AgCu50, pure copper, and pure silver,
respectively, was investigated by measuring the open circuit potentials using
anodic potentiodynamic polarization and potentiostatic method in 0.1 moldm-3
NaOH + 0.02 moldm-3 NaCl solution, without and with adding
2-mercaptobenzothiazole in various concentrations (0.00001 - 0.001 moldm-3).
Anodic polarization curves for AgCu50 alloy, showed four current peaks.
Potentiostatic curves showed that values of the stationary current densities
drop down with the increase of 2-mercaptobenzothiazole concentration in the
electrolyte. The electrode surface was analyzed by optical microscopy after
the potentiostatic oxidation. Micrographs confirmed that
2-mercaptobenzothiazole has got the inhibitory effect by forming the film of
CuMBT and AgMBT which protect the electrode surface from corrosion.
